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.
