Levallorphan
An opioid antagonist with properties similar to those of naloxone; in addition it also possesses some agonist properties. It should be used cautiously; levallorphan reverses severe opioid-induced respiratory depression but may exacerbate respiratory depression such as that induced by alcohol or other non-opioid central depressants.

Amabiline
Amabiline belongs to alkaloids and derivatives class of compounds. Those are naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic propertiesand is also some synthetic compounds of similar structure are attributed to alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus. Amabiline is soluble (in water) and a very weakly acidic compound (based on its pKa). Amabiline can be found in borage, which makes amabiline a potential biomarker for the consumption of this food product.
Histrionicotoxin
An azaspiro compound that is 1-azaspiro[5.5]undecane substituted by a hydroxy group at position 8, a but-1-en-3-yn-1-yl group at position 7 and a pent-3-en-1-yn-5-yl group at position 2 (the 2S,6R,7S,8S stereoisomer).
Supinine
Supinine is also known as spinin. Supinine is soluble (in water) and a very weakly acidic compound (based on its pKa). Supinine can be found in borage, which makes supinine a potential biomarker for the consumption of this food product.
alpha-Hydroxymetoprolol
alpha-Hydroxymetoprolol is a metabolite of metoprolol. Metoprolol is a selective β1 receptor blocker used in treatment of several diseases of the cardiovascular system, especially hypertension. The active substance metoprolol is employed either as metoprolol succinate or metoprolol tartrate (where 100 mg metoprolol tartrate corresponds to 95 mg metoprolol succinate). The tartrate is an immediate-release and the succinate is an extended-release formulation. (Wikipedia)
N-Dealkylated tolterodine
N-Dealkylated tolterodine is only found in individuals that have used or taken tolterodine. N-Dealkylated tolterodine is a metabolite of tolterodine. N-Dealkylated tolterodine belongs to the family of Diphenylmethanes. These are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups.
Octa-2,6-dienoylcarnitine
octa-2,6-dienoylcarnitine is an acylcarnitine. More specifically, it is an octa-2,6-dienoic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. octa-2,6-dienoylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine octa-2,6-dienoylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered.

AS19
AS19 is a potent, selective 5-HT7 receptor agonist with an IC50 value of 0.83 nM and a Ki of 0.6 nM. AS19 is selective for 5-HT7 over 5-HT1A, 5-HT1B, 5-HT1D, and 5-HT5A receptors (Kis = 89.7 nM, 490 nM, 6.6 nM and 98.5 nM, respectively). AS19 enhances memory consolidation and reverses Scopolamine- or Dizocilpine-induced amnesia[1][2][3].
