Meyers, Marvin J. published the artcile4-Aryl Pyrrolidines as Novel Orally Efficacious Antimalarial Agents. Part 2: 2-Aryl-N-(4-arylpyrrolidin-3-yl)acetamides, Formula: C9H10O3, the main research area is aryl pyrrolidinyl acetamide derivative preparation oral malaria.
Malaria is caused by infection from the Plasmodium parasite and kills hundreds of thousands of people every year. Emergence of new drug resistant strains of Plasmodium demands identification of new drugs with novel chemotypes and mechanisms of action. As a follow up to our evaluation of 4-aryl-N-benzylpyrrolidine-3-carboxamides as novel pyrrolidine-based antimalarial agents, we describe herein the structure-activity relationships of the reversed amide homologues 2-aryl-N-(4-arylpyrrolidin-3-yl)acetamides. Unlike their carboxamide homologues, acetamide pyrrolidines do not require a third chiral center to be potent inhibitors of P. falciparum and have good pharmacokinetic properties and improved oral efficacy in a mouse model of malaria. Compound (-)-32a (CWHM-1552) has an in vitro IC50 of 51 nM in the P. falciparum 3D7 assay and an in vivo ED90 of <10 mg/kg/day and ED99 of 30 mg/kg/day in a murine P. chabaudi model. Remarkably, the absolute stereochem. preference for this acetamide series (3S,4R) is opposite of that determined for the homologous carboxamide series. Lead compounds for this class have modest affinities for the hERG channel and inhibit CYP 3A4. Addnl. optimization is needed in order to eliminate these undesired properties from this otherwise promising series of antimalarial compounds ACS Medicinal Chemistry Letters published new progress about Antimalarials. 104-01-8 belongs to class isoquinoline, name is 4-Methoxyphenylacetic acid, and the molecular formula is C9H10O3, Formula: C9H10O3.
