A series of functionalized indolylalkylarenes were synthesized and their affinities for the serotonin transporter were investigated in vitro. Compounds I (R = H, F; R’ = 4-CF3Ph, 2-FBn, PhCH2CH2) were obtained by nucleophilic substitution of 3-(1H-indol-3-yl)propyl-4-methylbenzenesulfonates with a series of azaheterocycles. Compounds II (R = H, F; R’ = H, Cl, NO2) were prepared in a two-step sequence by reaction of 3-(1H-indol-3-yl)-2-methylpropanal with substituted 1,2-phenylenediamines. Compounds I (R = F; R’ = 4-CF3Ph, 2-FBn, PhCH2CH2) showed good binding affinities (Ki = 33.0, 48.0, and 17 nM, resp.).

A fragment-based lead discovery approach was used to discover novel ERK2 inhibitors. The crystal structure of N-benzyl-9H-purin-6-amine (compound 1) in complex with ERK2 elucidated its hinge-binding mode. In addition, the simultaneous binding of an imidazole mol. adjacent to (1) suggested a direction for fragment expansion. Structure-based core hopping applied to (1) led to 5H-pyrrolo[3,2-b]pyrazine that afforded direct vectors to probe the pockets of interest while retaining the essential hinge binding elements. Utilizing the new vectors for SAR exploration, the new core (I) was quickly optimized to 7-(1-benzyl-1H-pyrazol-4-yl)-2-(pyridin-4-yl)-5H-pyrrolo[3,2-b]pyrazine (compound 39) resulting in a greater than 6600-fold improvement in potency.

We present a novel series of selective androgen receptor modulators (SARMs) which shows excellent biol. activity and phys. properties. 1-(2-Hydroxy-2-methyl-3-phenoxypropanoyl)-indoline-4-carbonitriles showed potent binding to the androgen receptor (AR) and activated AR-mediated transcription in vitro. Representative compounds demonstrated diminished activity in promoting the intramol. interaction between the AR carboxyl (C) and amino (N) termini. This N/C-termini interaction is a biomarker assay for the undesired androgenic responses in vivo. In orchidectomized rats, daily administration of a lead compound from this series showed anabolic activity by increasing levator ani muscle weight Importantly, minimal androgenic effects (increased tissue weights) were observed in the prostate and seminal vesicles, along with minimal repression of circulating LH (LH) levels and no change in the lipid and triglyceride levels. This lead compound completed a two week rat toxicol. study, and was well tolerated at doses up to 100 mg/kg/day, the highest dose tested, for 14 consecutive days.

Application In Synthesis of 1-Butyl-1H-pyrazoleOn October 31, 1999 ,《Structural regularities governing sorption and gas chromatographic retention of aromatic nitrogen-containing heterocyclic compounds》 appeared in Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). The author of the article were Zhuravleva, I. L.; Kuz’menko, T. E.. The article conveys some information:

The regularities governing differences in the gas-chromatog. retention indexes of aromatic N-containing heterocyclic compounds were studied during gas-chromatog. anal. on a nonpolar capillary column. The retention indexes of pyrrole, pyrazole, imidazole, 1,2,4-triazole, oxazole, thiazole, isoxazole, pyridine, pyridazine, pyrimidine, pyrazine, and s-triazine and their alkyl derivatives depend on the number, nature, and arrangement of heteroatoms and alkyl groups in the cycles. The majority of homologous series of n-alkyl-substituted azoles and azines and n-alkylbenzenes is characterized by anomalously high differences between the retention indexes of Et and Me homologs. A scheme of calculating retention indexes of aromatic heterocyclic compounds from increments of heteroatoms was proposed. In the part of experimental materials, we found many familiar compounds, such as 1-Butyl-1H-pyrazole(cas: 52096-24-9Application In Synthesis of 1-Butyl-1H-pyrazole)

1-Butyl-1H-pyrazole(cas: 52096-24-9) belongs to pyrazoles. Pyrazoles and their related multiring analogs are common elements of a wide variety of bioactive compounds. These ring structures are rare in nature. A consequence of this is that they have previously been thought to be poor moieties to include in potential new drugs.
