  Novel 5α-reductase inhibitors. Synthesis and structure-activity studies of 5-substituted 1-methyl-2-pyridones and 1-methyl-2-piperidones

  摘要：

  In search for nonsteroidal inhibitors of 5 alpha-reductase for the treatment of benign prostatic hyperplasia (BPH) and possibly prostate cancer, substrate mimicks were synthesized comprising of a 1-methyl-2-pyridone (2, 4-16) or 1-methyl-2-piperidone (1, 3, 17-22) moiety (mimicking steroidal ring A) and a diisopropyl (1, 2, (E)-5-(E)-7, (Z)-5-(Z)-7, 11-13, 17-19) or a tert-butyl (3, 4, (E)-8-(E)-10, (Z)-8(Z)-10, 14-16, 20-22) benzamide (mimicking steroidal ring D). The bridge connecting the 5 and 4 positions of the rings consisted of amide (CONH: 1-4), ethenyl (CH=CH, CCH3=CH, CH=CH3: (E)-5-(E)-10, (Z)-5(Z)-10) or ethylene groups (CH2CH2, CHCH3CH2, CH2CHCH3: 11-22). The amides 1-4 were obtained by amidation of the carboxylic acid chlorides with the 4-amino-N-substituted benzamides. The ethenyl compounds (E)-5(E)-10 and (Z)-5-(Z)-10 were synthesized by Wittig reaction of the carbonyl compounds and the corresponding triphenylphosphonium salts and subsequent separation of the stereoisomers. Depending on the time of reaction, catalytic hydrogenation of the ethenyl isomers (E)-5-(E)-10 led to the pyridone-substituted ethylene compounds 11-16 as well as to the piperidone-substituted ethylene compounds 17-22. The 5 alpha-reductase inhibitory properties were determined using rat ventral prostate, as well as human BPH and prostate cancer as source, 1 beta,2 beta-[H-3]testosterone as substrate and a HPLC procedure for the separation of dihydrotestosterone (DHT). Tested at a concentration of 100 mu M, the inhibition values of 1-22 ranged from 0-99%. Significant differences were observed between rat and human enzyme. The most active compound was N,N-diisopropyl-4-[2-(1-methyl-2-oxo-piperidine-5-yl)ethylene]benzamide 17 (IC50: 13 mu M).

• An efficient method for the synthesis of 2-pyridones <i>via</i> C–H bond functionalization

  A simple and practical method to access N-substituted 2-pyridones via a formal [3+3] annulation of enaminones with acrylates based on RhIII-catalyzed C–H functionalization was developed. Control and deuterated experiments led to a plausible mechanism involving C–H bond cross-coupling and aminolysis cyclization. This strategy provides a short synthesis of structural motifs of N-substituted 2-pyridones

  开发了一种简单实用的方法，通过基于Rh III催化的C–H官能化，通过烯丙酮与丙烯酸酯的正式[3 + 3]环合反应，获得N-取代的2-吡啶酮。对照和氘代实验导致了一个合理的机制，涉及C–H键交叉偶联和氨解环化。该策略提供了N-取代的2-吡啶酮的结构基序的简短合成。
