  aim of improving its potency and physicochemical profile. The 6‐fluorobenzylideneindolinone 3‐12 bearing a 3′‐N‐propylaminosulfonyl substituent was found to be a promising substitute. Compound 3‐12 [6‐fluoro‐3‐(3′‐N‐propylaminosulfonylbenzylidene)‐1,3‐dihydroindol‐2‐one] was found to be tenfold more soluble than 4 and to have sub‐micromolar growth inhibitory activities on HCC cells. It is apoptogenic

  据报道，亚苄基吲哚酮6-氯-3-（3'-三氟甲基亚苄基）-1,3-二氢吲哚-2-一（4）对肝细胞癌（HCC）表现出有效的选择性生长抑制作用。证实性证据支持多受体酪氨酸激酶（RTK）抑制是一种可能的作用方式。然而，较差的物理化学性质4限制了它的赞助作为先导化合物。在这项研究中，对4的修饰进行了研究，以提高其效力和理化特性。发现带有3'- N-丙基氨基磺酰基取代基的6-氟亚苄基茚满酮3-12是有前途的替代品。化合物3-12 [6-氟-3-（3'-[N-丙基氨基磺酰基亚苄基] -1,3-二氢吲哚-2-1]的溶解度是4的十倍，并且对HCC细胞具有亚微摩尔的生长抑制活性。它具有凋亡作用，可抑制HuH7中多个RTK的磷酸化，其中对FGFR4和HER3的抑制作用尤为明显。在生理相关的原位HCC异种移植小鼠模型中，化合物3-12降低了肿瘤负荷。构效关系支持氟和N'-丙基氨基磺酰基部分在增强基于细胞的活性和
• Novel synthesis of oxindole quinazolines using solid phase multiparallel chemistry
  作者：Laurent F Hennequin、Sylvie Piva-Le Blanc

  日期：1999.5

  A novel synthesis of oxindole quinazolines modified at the C4 and C7 positions via solid phase multiparallel chemistry is described. The C7 position of the quinazoline was modified by Mitsunobu reaction and the introduction of the key C4-oxindole ring was achieved at the final stage of the synthesis and constituted the cleavage step from the resin. Purification of the final products was easily achieved
