CPI-613 CPI-613 is a racemic mixture of the enantiomers of a synthetic alpha-lipoic lipoic acid analogue with potential chemopreventive and antineoplastic activities. Although the exact mechanism of action is unknown, alpha-lipoic acid analogue CPI-613 has been shown to inhibit metabolic and regulatory processes required for cell growth in solid tumors. Both enantiomers in the racemic mixture exhibit antineoplastic activity. The mechanism-of-action of CPI-613 appears distinct from the current classes of anti-cancer agents used in the clinic. CPI-613 demonstrates both in vitro and in vivo anti-tumor activity. CPI-613 was known to strongly disrupt tumor mitochondrial metabolism. CPI-613 disruption of tumor mitochondrial metabolism is followed by efficient commitment to cell death by multiple, apparently redundant pathways, including apoptosis, in all tested cancer cell lines. Further, CPI-613 shows strong antitumor activity in vivo against human non-small cell lung and pancreatic cancers in xenograft models with low side-effect toxicity. Group: Pharmaceutical. Alternative Names: CPI613; CPI 613; Devimistat; 6,8-bis(benzylthio)octanoic acid. CAS No. 95809-78-2. Pack Sizes: 250 mg. Product ID: B1370-103006. Molecular formula: C22H28O2S2. Mole weight: 388.59.

Escitalopram Escitalopram, the S-enantiomer of citalopram, belongs to a class of antidepressant agents known as selective serotonin-reuptake inhibitors (SSRIs). Escitalopram may be used to treat major depressive disorder (MDD) and generalized anxiety disorder (GAD). Escitalopram has no significant affinity for adrenergic (alpha1, alpha2, beta), cholinergic, GABA, dopaminergic, histaminergic, serotonergic (5HT1A, 5HT1B, 5HT2), or benzodiazepine receptors; antagonism of such receptors has been hypothesized to be associated with various anticholinergic, sedative, and cardiovascular effects for other psychotropic drugs. The chronic administration of escitalopram is found to downregulate brain norepinephrine receptors, as has been observed with other drugs effective in the treatment of major depressive disorder. Escitalopram does not inhibit monoamine oxidase. Uses: Serotonin uptake inhibitors; antidepressive agents, second-generation. Group: Pharmaceutical. Alternative Names: (S)-Citalopram; S-(+)-Citalopram; Seroplex. CAS No. 128196-01-0. Pack Sizes: 500 mg. Product ID: B2693-461840. Molecular formula: C20H21FN2O. Mole weight: 324.39.
