antiproliferative activity on DU‐145 human prostate carcinoma cell line (hit compound potency – 2.9 μM). Medicinal chemistry optimization of two peripheral diversity vectors of the hit molecule, independently, led to SAR generalizations and identification of the ‘best’ moieties. The latter were merged in a single compound that exhibited an over 100‐fold better potency than the hit compound. For the most potent
通过高通量筛选确定了一个新的化学系列,它对 DU-145 人前列腺癌细胞系具有抗增殖活性(命中化合物效力 - 2.9 μM)。对命中分子的两个外围多样性载体的药物化学优化,独立地导致 SAR 概括和“最佳”部分的鉴定。后者合并为单一化合物,其效力比命中化合物高 100 倍以上。对于最有效的化合物,已证实观察到的抗增殖效力与化合物的非特异性细胞毒性无关。

A carbene-catalyzed enantio- and diastereoselective [2 + 4] cycloaddition reaction is developed for quick and efficient access to structurally complex multicyclic pyrano[2,3-c]pyrazole molecules. The reaction tolerates a broad scope of substrates bearing various substitution patterns, with the multicyclic pyrano[2,3-c]pyrazole products afforded in generally good to excellent yields and optical purities
开发了一种卡宾催化的对映选择性和非对映选择性 [2 + 4] 环加成反应,用于快速有效地获得结构复杂的多环吡喃并 [2,3- c ] 吡唑分子。该反应可以耐受具有各种取代模式的广泛底物,多环吡喃并[2,3- c ]吡唑产物的产率和光学纯度一般都很好。从这种方法获得的手性分子在开发用于植物保护的新型杀菌剂方面具有广阔的应用前景。

Meerwein reaction of arenediazonium chlorides with acrolein gave 3-aryl-2-chloropropanals which were brought into cyclocondensation with thiourea. The resulting 2-amino-5-benzyl-1,3-thiazoles were acylated with carboxylic acid chlorides and plithalic anhydride to afford, respectively, 2-acylamino-5-benzyl-1,3-thiazoles and N-(5-benzyl- 1,3-thiazol-2-yl)phthalimides.
