A series of 4-aminopyrimidines (1) was identified as novel HIV inhibitors of unknown molecular target. Structural modifications were carried out to establish its SAR and identify the linking site for target identification. A number of analogs were found to possess single digit inhibitory activity for HIV replication. Several analogs with various potential linkers, including a biotinated analog, also exhibited excellent potency, and could serve as tools for the identification of novel anti-HTV targets.

were found to catalyze the direct reductive amination of aromatic and aliphatic ketones under mild conditions at 0.5 mol % loading with high selectivity towards primary amines. One of the complexes was found to be active in both the Leuckart–Wallach (NH4CO2H) type reaction as well as in the hydrogenative (H2/NH4AcO) reductive amination. The protocol with ammoniumformate does not require an inert atmosphere
发现带有双齿尿素-磷配体的半三明治铱络合物在温和的条件下以0.5 mol%的负载量对伯胺具有高选择性,可催化芳香族和脂肪族酮的直接还原胺化。发现该配合物之一在Leuckart-Wallach(NH 4 CO 2 H)型反应以及氢化(H 2 / NH 4 AcO)还原胺化反应中均具有活性。使用甲酸铵的方案不需要惰性气氛,干燥溶剂以及添加剂,并且与以前的报道相反,是在六氟异丙醇(HFIP)而不是甲醇中进行的。施加NH 4 CO 2 D或D 2 导致氘高度掺入伯胺α-位置。

This invention relates to CXCR4 inhibitors and their use in treating and/or preventing a variety of angiogenic, microvascular and ocular disorders including primary indications for diabetic retinopathy, macular degeneration (such as wet or neovascular age-related macular degeneration (AMD) and dry or atrophic AMD), macular edema, and secondary indications for inhibiting tumor vascularization, and corneal and iris neovascularization.
The amidinophenylurea scaffold was earlier shown to provide an excellent template for the synthesis of novel and potent inhibitors of the blood coagulation factor VIIa. In this contribution we describe the structure-based design of potent ligands guided by X-ray crystallography, molecular modeling and docking studies. The design and synthetic efforts were directed towards novel modifications to explore the protease binding region close to the S4 subsite. (C) 2004 Elsevier Ltd. All rights reserved.
