The synthesis and structure-activity relationships of a novel series of aroylpyrrole alkylamindes as potent selective bradykinin 132 receptor antagonists are described. Several members of this series display nanomolar affinity at the B-2 receptor and show activity in an animal model of antinociception. (C) 2003 Elsevier Science Ltd. All rights reserved.

(EN) This invention is related to: (1) an inhibitory agent on 5$g(a)-reductase which comprises a five membered heterocyclic compound of formula (Ia), and non-toxic salts thereof as active ingredient; (2) a five membered heterocyclic compound of formula (Ib), and non-toxic salts thereof; (3) process for the preparation of a five membered heterocyclic ring compound of formula (Ib) and non-toxic salts thereof. The compounds of formula (Ia) are useful for the prevention and treatment of diseases induced by the excess generation of dihydrotestosterone in mammals, for example, alopecia (androgenic alopecia), acnes, hypertrophy of prostate and prostatic cancer.(FR) Cette invention se rapporte: (1) à un agent inhibiteur agissant sur la 5$g(a)-réductase, cet agent comprenant comme principe actif un composé hétérocyclique à cinq éléments représenté par la formule (Ia), ainsi que des sels non toxiques de ce composé; (2) à un composé hétérocyclique à cinq éléments représenté par la formule (Ib), ainsi que des sels non toxiques de ce composé; (3) et à un procédé pour préparer un composé à chaînes fermées hétérocycliques à cinq éléments, représenté par la formule (Ib), ainsi que des sels non toxiques de ce composé. Le composé de la formule (Ia) sert à prévenir et à traiter les maladies induites par la production excessive de dihydrotestostérone chez les mammifères, telles que l'alopécie (alopécie endrogène), l'acné, l'hypertrophie de la prostate et le cancer de la prostate.
3-(4-Aroyl-1-methyl-1<i>H</i>-2-pyrrolyl)-<i>N</i>-hydroxy-2-propenamides as a New Class of Synthetic Histone Deacetylase Inhibitors. 2. Effect of Pyrrole-C<sub>2</sub> and/or -C<sub>4</sub> Substitutions on Biological Activity
pyrrole-C2 ethene chains of 1a-c, which were replaced with methylene, ethylene, substituted ethene, and 1,3-butadiene chains (compounds 2). Biological results clearly indicated the unsubstituted ethene chain as the best structural motif to get the highest HDAC inhibitory activity, the sole exception to this rule being the introduction of the 1,3-butadienyl moiety into the 1a chemical structure (IC50(2f)
