  Design, Synthesis, and Biological Evaluation of Novel Potent and Selective α_vβ₃/α_vβ₅ Integrin Dual Inhibitors with Improved Bioavailability. Selection of the Molecular Core

  摘要：

  A novel series of potent and selective alpha(v)beta(3)/alpha(v)beta(5) dual inhibitors was designed, synthesized, and evaluated against several integrins. These compounds were synthesized through a Mitsunobu reaction between the guanidinium mimetics and the corresponding central templates. Guanidinium mimetics with enhaced rigidity (i.e., (2-pyridylamino)propoxy versus the 2-(6-methylamino-2-pyridyl)ethoxy) led to improved activity toward alpha(v)beta(3). Exemplary oral bioavailability in mice was achieved using the indole central scaffold. Although, oral bioavailability was maintained when the indole molecular core was replace with the bioisosteric benzofuran or benzothiophene ring systems, it was found to not significantly impact the integrin activity or selectivity. However, the indole series displayed the best in vivo pharmacokinetic properties. Thus, the indole series was selected for further structure-activity relationships to obtain more potent alpha(v)beta(3)/alpha(v)beta(5) dual antagonist with improved oral bioavailability.

• Practical, environment-benign and atom economic KOAc-catalysed deprotection of aryl TIPS ethers under mild fluoride-free conditions
  作者：Bing Wang、Hui-Xia Sun、Bo Chen、Zhi-Hua Sun

  DOI：10.1039/b905443j

  日期：——

  A KOAc-catalysed, fluoride-free protocol not only effects chemoselective deprotection of phenolic TIPS ethers without affecting acetal, ketal, carbamate, O-acetyl and aliphatic silyl ethers, but also improves its atom economy by recycling the silanol byproduct.

  一种以KOAc为催化剂、无氟的反应程序，不仅能够化学选择性地去保护苯醇TIPS醚，而不影响缩醛、缩酮、氨基甲酸酯、O-乙酰基和脂肪族硅醚，还通过回收硅醇副产物改善了其原子经济性。
