C25H27NO2 (373.2042)

Endoxifen (EDX) is a key active metabolite of tamoxifen (TAM) with higher affinity and specificity to estrogen receptors that also inhibits aromatase activity. (PMID: 23274567) Tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, hydroxytamoxifen. In other tissues such as the endometrium, it behaves as an agonist, and thus may be characterized as a mixed agonist/antagonist. Tamoxifen is the usual endocrine therapy for hormone receptor-positive breast cancer in pre-menopausal women, and is also a standard in post-menopausal women although aromatase inhibitors are also frequently used in that setting. (Wikipedia) The pharmacological activity of Tamoxifen is dependent on its conversion to its active metabolite, endoxifen, by CYP2D6. (PMID: 23711794) Tamoxifen is a largely inactive pro-drug, requiring metabolism into its most important metabolite endoxifen. Since the cytochrome P450 (CYP) 2D6 enzyme is primarily involved in this metabolism, genetic polymorphisms of this enzyme, but also drug-induced CYP2D6 inhibition can result in considerably reduced endoxifen formation and as a consequence may affect the efficacy of tamoxifen treatment.

Autumnaline

(1S)-1-[2-(3-hydroxy-4,5-dimethoxyphenyl)ethyl]-6-methoxy-2-methyl-3,4-dihydro-1H-isoquinolin-7-ol

C21H27NO5 (373.1889)

(S)-Autumnaline is an isoquinoline alkaloid. (S)-autumnaline has been reported in Colchicum autumnale, Colchicum ritchii Autumnaline is a natural organic compound classified as a protoberberine alkaloid, which is a subset of the larger category of alkaloids. It is primarily derived from plants, particularly those of the Colchicum genus, including Colchicum autumnale. This compound shares structural similarities with other alkaloids, such as colchicine, and is known for its potential biological activities. The biological functions of autumnaline are not as extensively studied as those of colchicine, but research suggests it may have several notable effects: Cytotoxic Properties: Like many alkaloids, autumnaline exhibits cytotoxicity, meaning it has the ability to damage or inhibit the growth of cells. This property could be exploited in cancer research, as cytotoxic compounds are often investigated for their potential to Inhibit tumor growth. Antioxidant Activity: Some studies have indicated that autumnaline may possess antioxidant properties. Antioxidants are important in protecting cells from damage caused by reactive oxygen species, which are implicated in various diseases and aging processes. Anti-inflammatory Effects: There is emerging evidence suggesting that certain alkaloids, including some protoberberine alkaloids, may have anti-inflammatory effects. This could be significant in the context of treating inflammatory conditions. Potential Medicinal Uses: Due to its complex structure and biological activities, autumnaline could be of interest for medicinal purposes. However, further research is needed to fully understand its potential therapeutic applications, as well as its safety and efficacy.

Target: Histamine Receptor Olopatadine hydrochloride (ALO4943A) is one of the second-generation histamine H1 receptor antagonists that are treated for allergic disorders. Olopatadine hydrochloride (ALO4943A) significantly inhibited the ear swelling and the increased production of IL-4, IL-1beta, IL-6, GM-CSF and NGF in the lesioned ear [1]. Olopatadine hydrochloride (ALO4943A) was highly and rapidly absorbed in healthy human volunteers. The urinary excretion of Olopatadine hydrochloride (ALO4943A) accounted for not less than 58\% and the contribution of metabolism was considerably low in the clearance of olopatadine in humans. Olopatadine hydrochloride (ALO4943A) is one of the few renal clearance drugs in antiallergic drugs. Olopatadine hydrochloride (ALO4943A) was shown to be useful for the treatment of allergic rhinitis and chronic urticaria in double-blind clinical trials [2]. Olopatadine hydrochloride (ALO4943A) inhibits histamine release in a concentration-dependent fashion (IC50 = 559 microM) from human conjunctival mast cell preparations in vitro. Passive anaphylaxis in guinea pig conjunctiva was attenuated by Olopatadine hydrochloride (ALO4943A) applied 30 min prior to intravenous or topical ocular antigen challenge (ED50 values 0.0067\% and 0.0170\%, w/v, respectively) [3].
