Rolapitant (SCH619734) Hydrochloride is the hydrochloride salt form of rolapitant, an orally bioavailable, centrally-acting, selective, neurokinin 1 receptor (NK1-receptor) antagonist with potential antiemetic activity. Upon oral administration, rolapitant competitively binds to and blocks the activity of the NK1-receptor in the central nervous system, thereby inhibiting the binding of the endogenous ligand, substance P (SP). This may prevent both SP-induced emesis and chemotherapy-induced nausea and vomiting (CINV). The interaction of SP with the NK1-receptor plays a key role in the induction of nausea and vomiting caused by emetogenic cancer chemotherapy. Compared to other NK1-receptor antagonists, rolapitant has both a more rapid onset of action and a much longer half-life.

8-Demethyl Ivabradine, a metabolite of Ivabradine, is an orally bioavailable cyclic nucleotide-gated (HCN) channel blocker with hyperpolarization-activated properties[1].

8-hydroxy Efavirenz is a major oxidative metabolite of the non-nucleoside reverse transcriptase inhibitor efavirenz . 8-hydroxy Efavirenz is formed when efavirenz is metabolized by the cytochrome P450 (CYP) isoform CYP2B6. It induces apoptosis in rat primary hippocampal neurons and loss of dendritic spines in rat primary hippocampal neuronal cultures when used at a concentration of 0.01 μM.

8-Isoprostaglandin F2α is a non-enzymatically generated isoprostane derived from arachidonic acid peroxidation in membrane phospholipids, present in human plasma in both esterified and free acid forms. 8-Isoprostaglandin F2α functions as a weak thromboxane prostanoid receptor agonist in vascular smooth muscle, making it a reliable biomarker of oxidative stress.

Resolvin D1 is produced physiologically from the sequential oxygenation of docosahexaenoic acid by 15- and 5-lipoxygenase . It reduces human polymorphonuclear leukocyte transendothelial migration, the earliest event in acute inflammation, with an EC50 value of ~30 nM. RvD1 methyl ester is a methyl ester version of the free acid that may act as a lipophilic prodrug form that will alter its distribution and pharmacokinetic properties. The methyl ester moiety is susceptible to cleavage by intracellular esterases, leaving the free acid.
