Methods of identifying target binding molecules by target guided synthesis are provided. The methods include providing two or more fragments capable of reacting to form the target binding molecule and mixing the fragments with the target. The methods can be used to identify target binding molecules that bind targets such as proteins or nucleic acids, including those that bind shallow binding pockets on the surface of such targets. The methods are applied to the Bcl-XL and Mcl-1 proteins from the Bcl-2 family of proteins. Using thio acid and sulfonyl azide fragments capable of reacting through sulfo-click chemistry, new acyl sulfonamides are identified that bind one or both of the Bcl-XL and Mcl-1 proteins. Pharmaceutical formulations of these target binding molecules are also provided.
提供了通过靶标引导合成鉴定靶标结合分子的方法。这些方法包括提供两种或两种以上能够反应形成目标结合分子的片段,并将这些片段与目标物混合。这些方法可用于鉴定与蛋白质或核酸等靶标结合的靶标结合分子,包括与这些靶标表面浅结合口袋结合的分子。这些方法适用于 Bcl-2 蛋白家族中的 Bcl-XL 和 Mcl-1 蛋白。利用
