Azelaic acid
Nonanedioic acid is an alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. It has a role as an antibacterial agent, an antineoplastic agent, a dermatologic drug and a plant metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of an azelaate(2-) and an azelaate. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is also produced by Malassezia furfur, also known as Pityrosporum ovale, which is a species of fungus that is normally found on human skin. Azelaic acid is effective against a number of skin conditions, such as mild to moderate acne, when applied topically in a cream formulation of 20\\\\\%. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear. Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. Azelaic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). The physiologic effect of azelaic acid is by means of Decreased Protein Synthesis, and Decreased Sebaceous Gland Activity. Azelaic Acid is a naturally occurring dicarboxylic acid produced by Malassezia furfur and found in whole grain cereals, rye, barley and animal products. Azelaic acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant activity. Azelaic acid is bactericidal against Proprionibacterium acnes and Staphylococcus epidermidis due to its inhibitory effect on the synthesis of microbial cellular proteins. Azelaic acid exerts its keratolytic and comedolytic effects by reducing the thickness of the stratum corneum and decreasing the number of keratohyalin granules by reducing the amount and distribution of filaggrin in epidermal layers. Azelaic acid also possesses a direct anti-inflammatory effect due to its scavenger activity of free oxygen radical. This drug is used topically to reduce inflammation associated with acne and rosacea. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley.

Azelaic acid (AZA) is a naturally occurring saturated nine-carbon dicarboxylic acid (COOH (CH2)7-COOH). It possesses a variety of biological actions both in vitro and in vivo. Interest in the biological activity of AZA arose originally out of studies of skin surface lipids and the pathogenesis of hypochromia in pityriasis versicolor infection. Later, it was shown that Pityrosporum can oxidize unsaturated fatty acids to C8-C12 dicarboxylic acids that are cornpetitive inhibitors of tyrosinase in vitro. Azelaic acid was chosen for further investigation and development of a new topical drug for treating hyperpigmentary disorders for the following reasons: it possesses a middle-range of antityrosinase activity, is inexpensive, and more soluble to be incorporated into a base cream than other dicarboxylic acids. Azelaic acid is another option for the topical treatment of mild to moderate inflammatory acne vulgaris. It offers effectiveness similar to that of other agents without the systemic side effects of oral antibiotics or the allergic sensitization of topical benzoyl peroxide and with less irritation than tretinoin. Azelaic acid is less expensive than certain other prescription acne preparations, but it is much more expensive than nonprescription benzoyl peroxide preparations. Whether it is safe and effective when used in combination with other agents is not known. (PMID: 7737781, 8961845). An alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. Plants biology In plants, azelaic acid serves as a "distress flare" involved in defense responses after infection.[7] It serves as a signal that induces the accumulation of salicylic acid, an important component of a plant's defensive response.[8] Human biology The mechanism of action in humans is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37.[9] Polymers and related materials Esters of this dicarboxylic acid find applications in lubrication and plasticizers. In lubricant industries it is used as a thickening agent in lithium complex grease. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which finds specialized uses as a plastic.[4] Medical Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.[10][11] It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth[clarification needed] of acne bacteria.[12] Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation.[11] It clears the bumps and swelling caused by rosacea. In topical pharmaceutical preparations and scientific research AzA is typically used in concentrations between 15\\\% and 20\\\% but some research demonstrates that in certain vehicle formulations the pharmaceutical effects of 10\\\% Azelaic acid has the potential to be fully comparable to that of some 20\\\% creams.[13] Acne treatment Azelaic acid is effective for mild to moderate acne when applied topically at a 15\\\%-20\\\% concentration.[14][15][16][17] In patients with moderate acne, twice daily application over 3 months of 20\\\% AzA significantly reduced the number of comedones, papules, and pustules;[18][19] at this strength, it’s considered to be as effective as benzoyl peroxide 5\\\%, tretinoin 0.05\\\%, erythromycin 2\\\%, and oral tetracycline at 500 mg-1000 mg.[20][21] In a comparative review of effects of topical AzA, Salicylic acid, Nicotinamide, Sulfur, Zinc, and alpha-hydroxy acid, AzA had more high-quality evidence of effectiveness than the rest.[22] Results can be expected after 4 weeks of twice-daily treatment. The effectiveness of long term use is unclear, but it’s been recommended that AzA be used for at least 6 months continuously for maintenance.[20] Whitening agent Azelaic acid is used for treatment of skin pigmentation, including melasma and postinflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone.[23] As a tyrosinase inhibitor,[5] azelaic acid reduces synthesis of melanin.[24] According to one report in 1988, azelaic acid in combination with zinc sulfate in vitro was found to be a potent (90\\\% inhibition) 5α-reductase inhibitor, similar to the hair loss drugs finasteride and dutasteride.[25] In vitro research during mid-1980s evaluating azelaic acid's depigmenting (whitening) capability concluded it is effective (cytotoxic to melanocytes) at only high concentrations.[26] A 1996 review claimed 20\\\% AzA is as potent as 4\\\% hydroquinone after a period of application of three months without the latter's adverse effects and even more effective if applied along with tretinoin for the same period of time.[27][19] Azelaic acid is a nine-carbon dicarboxylic acid. Azelaic acid has antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis through inhibition of microbial cellular prorein synthesis. Azelaic acid has hypopigmentation action resulting from its ability to scavenge free radicals[1][2]. Azelaic acid is a nine-carbon dicarboxylic acid.

Nα-Acetyl-L-lysine
N-epsilon-Acetyl-L-lysine also known as Nepsilon-Acetyllysine or N6-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at one of its nitrogen atoms. N-epsilon-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-epsilon-Acetyl-L-lysine is a biologically available sidechain, N-capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-epsilon-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-epsilon-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins (often histones) by specific hydrolases. N-epsilon-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Post-translational lysine-acetylation is one of two major modifications of lysine residues in various proteins – either N-terminal or N-alpha acetylation or N6 (sidechain) acetylation. Side-chain acetylation of specific lysine residues in the N-terminal domains of core histones is a biochemical marker of active genes. Acetylation is now known to play a major role in eukaryotic transcription. Specifically, acetyltransferase enzymes that act on particular lysine side chains of histones and other proteins are intimately involved in transcriptional activation. By modifying chromatin proteins and transcription-related factors, these acetylases are believed to regulate the transcription of many genes. The best-characterized mechanism is acetylation, catalyzed by histone acetyltransferase (HAT) enzymes. HATs function enzymatically by transferring an acetyl group from acetyl-coenzyme A (acetyl-CoA) to the amino group of certain lysine side chains within a histones basic N-terminal tail region. Within a histone octamer, these regions extend out from the associated globular domains, and in the context of a nucleosome, they are believed to bind the DNA through charge interactions (positively charged histone tails associated with negatively charged DNA) or mediate interactions between nucleosomes. Lysine acetylation, which neutralizes part of a tail regions positive charge, is postulated to weaken histone-DNA or nucleosome-nucleosome interactions and/or signal a conformational change, thereby destabilizing nucleosome structure or arrangement and giving other nuclear factors, such as the transcription complex, more access to a genetic locus. In agreement with this is the fact that acetylated chromatin has long been associated with states of transcriptional activation. Specific recognition of N6-acetyl-L-lysine is a conserved function of all bromodomains found in different proteins, recognized as an emerging intracellular signalling mechanism that plays critical roles in regulating gene transcription, cell-cycle progression, apoptosis, DNA repair, and cytoskeletal organization (PMID: 9169194 , 10827952 , 17340003 , 16247734 , 9478947 , 10839822 ). N-acetylated amino acids, such as N-epsilon-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from histones going through proteolytic degradation (PMID: 16465618). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Isolated from sugarbeet (Beta vulgaris) KEIO_ID A174 Nepsilon-Acetyl-L-lysine is a derivative of the amino acid lysine.

N2-acetyllysine
N-alpha-Acetyl-L-lysine also known as Nalpha-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-alpha-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-alpha-Acetyl-L-lysine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-alpha-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-alpha-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\% of all human proteins and 68\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-alpha-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free lysine can also occur. In particular, N-alpha-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Individuals with hyperlysinaemia due to L-lysine alpha-ketoglutarate reductase deficiency will excrete high levels of N-alpha-Acetyl-L-lysine in their urine (PMID: 116084). L-lysine alpha-ketoglutarate reductase deficiency, if untreated, can lead to neurological and behavioral deficits (PMID: 116084). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Acetyl-L-lysine is an endogenous metabolite.

Nonate
Nonic acid or the anion, nonate, is a derivative of succinic acid, which is a dicarboxylic acid. The anion, succinate, is a component of the citric acid cycle capable of donating electrons to the electron transfer chain.

SDH with a covalently attached FAD prosthetic group, binds enzyme substrates (succinate and fumarate) and physiological regulators (oxaloacetate and ATP). Oxidizing succinate links SDH to the fast-cycling Krebs cycle portion where it participates in the breakdown of acetyl-CoA throughout the whole Krebs cycle. The succinate can readily be imported into the mitochondrial matrix by the n-butylmalonate- (or phenylsuccinate-) sensitive dicarboxylate carrier in exchange with inorganic phosphate or another organic acid, e. g. malate. (PMID 16143825) Mutations in the four genes encoding the subunits of the mitochondrial respiratory chain succinate dehydrogenase are associated with a wide spectrum of clinical presentations (i.e.: Huntingtons disease.

Indolepropionamide
Indolepropionamide (IPAM) is a product of tryptophan metabolism formed by symbiotic bacteria in the gastrointestinal tract of mammals. In particular, IPAM is an amide derivatization product of indole-3-propionic acid (IPA). IPAM reduces reactive oxygen species by inhibiting oxidative phosphorylation in complex I of the electron transport chain and acts as a stabilizer of energy metabolism, thereby reducing reactive oxygen species (ROS) production. In contrast to indole-3-propionic acid which bears a polar carboxyl group that is ionized at physiological pH carrying a negative charge, IPAM is non-polar and has sufficient lipophilicity to penetrate through biological membranes. In contrast to melatonin, IPAM is a "reversed amide" lacking the methoxy group as an aromatic substituent. In contrast to IPAM, melatonin is quickly metabolized in the liver by hydroxylation and excreted as the glucuronide or sulfate conjugate of 6-hydroxymelatonin (a pro-oxidant metabolite). IPAM, however, has a long half-life and no pro-oxidant activity (PMID: 20421998).
