Cholesterol Surrogates Incorporating a Benzophenone as Part of the Sterol Tetracycle
摘要:
Photoactivatable analogues 4-6 of cholesterol (1), having their cross-linking site in the ring D sterol region, have been synthesized starting from bromotetralone 14 via enantioselective Robinson annulation to enone 13 and Suzuki carbonylative coupling to the appropriate phenylboronic acid. Each of 4-6 was shown to substitute successfully for 1 in an assay of apo A-I-induced cellular cholesterol efflux, indicating that these analogues equilibrated with 1 in all major cellular pools.

There is disclosed pyridine- and pyrimidinecarboxamide compounds useful as pharmaceutical agents, synthesis processes, and pharmaceutical compositions which include pyridine- and pyrimidinecarboxamides compounds. More specifically, there is disclosed a genus of CXCR2 inhibitor compounds that are useful for treating a variety of inflammatory and neoplastic disorders.
Benzoyl urea derivatives that are alpha helical peptides mimetics that mimic BH3-only proteins, compositions containing them, their conjugation to cell-targeting-moieties, and their use in the regulation of cell death are disclosed. The benzoyl urea derivatives are capable of binding to and neutralizing pro-survival Bcl-2 proteins. Use of benzoyl urea derivatives in the treatment and/or prophylaxis of diseases or conditions associated with deregulation of cell death are also described.

lysosomes. In this study, we show that the homologous members of the human Atg8 family proteins, LC3A and LC3B, are druggable by a small molecule inhibitor novobiocin. Structure–activityrelationship (SAR) studies of the 4-hydroxy coumarin core scaffold were performed, supported by a crystalstructure of the LC3A dihydronovobiocin complex. The study reports the first nonpeptideinhibitors for these protein
