Acylcarnitine analogues as topical, microbicidal spermicides.
摘要:
Acylcarnitine analogues, (+)-6-Carboxylatomethyl-2-alkyl-4,4-dimethylmorpholinium (Z-n, where n = the number of carbons in the alkyl chain), synthesized in multi-gram quantities show in vitro activities as spermicides, anti-HIV agents, and inhibitors of the growth of Candida albicans. Activity improves with increasing chain length. Compound Z-15 is a candidate for further study as a topical, microbicidal spermicide. (C) 1999 Elsevier Science Ltd. All rights reserved.

The reaction of lithio bromomethyl phenyl sulfoxide with aldehydes gave the corresponding β-hydroxy-α-bromosulfoxides. Pyrolysis of these hydroxysulfoxides yielded the expected bromemethyl ketones in excellent yields.

A second-generationlibrary of 2-aminoimidazole-based derivatives incorporating a "reversed amide" (RA) motif in comparison to the marine natural product oroidin were synthesized and subsequently assayed for antibiofilmactivity against the medically relevant Gram-negative proteobacteria P. aeruginosa and A. baumannii. Most notably, an in-depth activity profile is reported for the most active subclass

Two fluorinated nonhydrolyzable analogs of myristoyl-coenzyme A were synthesized and tested for inhibitory activity against N-myristoyltransferase (NMT). S-(2,2-Difluoro-3-oxohexadecyl)-coenzyme A (3) and S-(3,3-difluoro-2-oxopentadecyl)-coenzyme A (2) were prepared by alkylation of coenzyme A and were purified by reverse phase chromatography. Inhibition of NMT was observed with 3 and 2, with IC50's of 110 nM and 80 nM, respectively, in an in vitro assay developed in our laboratory. The known unfluorinated analog S-(2-oxopentadecyl)-coenzyme A (1) was found to have an IC50 of 7 nM. At 100 mu M in D2O, 3 was 59% hydrated and 2 was 88% hydrated.
