Evacetrapib (LY2484595) is a novel benzazepine-based CETP inhibitor that has been developed at Lilly Research Laboratories. Evacetrapib inhibits CETP with IC50 of 5.5 nM, elevates HDL cholesterol without increases in aldosterone or blood pressure. Phase 3. On 01 Sep 2016 Eli Lilly terminates the phase III ACCENTUATE trial in Hyperlipidaemia (Adjunctive treatment) in USA and Puerto Rico (PO) due to insufficient efficacy (NCT02227784).

Cidoxepin is the cis-isomer of the widely prescribed tricyclic compound doxepin. Commercial preparations of the tricyclic anti-depressant doxepin contain 15% of the more active cis-doxepin and 85% of the trans-isomer. Elorac, Inc., a rapidly growing specialty pharmaceutical company focused on the treatment of dermatological disorders, is pleased to announce that it has acquired worldwide rights to the active agent Cidoxepin from Gideon Pharmaceuticals. Cidoxepin appears to be much more potent than doxepin while having less sedative and cholinergic side effects. Elorac plans to develop oral formulations of the drug to treat urticaria and topical formulations for treatment of atopic and contact dermatitis.

S-fluoxetine is an enantiomer of fluoxetine, a potent and selective inhibitor of the neuronal serotonin-uptake carrier and a clinically effective antidepressant. R-fluoxetine and S-fluoxetine enantiomers are nearly equipotent at blocking serotonin reuptake. In all biochemical and pharmacological studies, the eudismic ratio for the fluoxetine enantiomers is also near unity. A study examining the relative contributions of CYP enzymes to the metabolism of S-fluoxetine, and R-fluoxetine found dramatic differences. These data led to discovery programs between Lilly and Sepracor for the individual enantiomers. S-fluoxetine was studied in a phase 2 clinical trial for the prophylaxis of migraine, however, development was discontinued.

Naftopidil,(R)- is an enantiomer of Naftopidil (NAF), a specific subtype selective α1-adrenoceptor blocker. Racemic Naftopidil is frequently used for the treatment of lower urinary tract symptoms/benign prostatic hyperplasia. No significant differences in pharmacokinetic parameters were observed between R(+)- and S(−)-NAF after intravenous administration. However, mean plasma concentrations of R(+)-NAF were lower than those of S(-)-NAF after intragastric administration. R(+)-NAF bioavailability in rats was consistently about two-fold lower than that of S(-)-NAF. The fractions of R(+)- NAF reaching the prostate and metabolized in the liver were higher than those of S(−)-NAF. The major pathways of R(+)- NAF metabolism in vitro were demethylation and hydroxylation. CYP2C9 played the most important role in the demethylation and hydroxylation of both NAF enantiomers. CYP2C19 was another CYP isoform that played a major role in R(+)-NAF metabolism.

Palmatine is a protoberberine alkaloid. Palmatine is major component of herbal preparations mainly used in traditional medicine Chinese, Korean and Indian. Palmatine can be found in various medicinal plants such as Coptis chinensis, Rhizoma coptidis, Corydalis yanhusuo, Radix tinosporae, among others. It exerts diverse pharmacological and biological properties. Palmatine has been proposed as a promising DNA phototherapy drug, notably due to its ability to produce in situ singlet oxygen only when interacting with DNA.
