ACS OMEGA 2019; 4:11914-11920. [PMID: 31460302 PMCID: PMC6681978 DOI: 10.1021/acsomega.9b01044] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Accepted: 06/26/2019] [Indexed: 06/10/2023]
Abstract
We describe a rapid electrophoresis-based method for profiling of carbonic anhydrase inhibitors. In addition to the pharmacophore moiety intended for reversible interaction with a target enzyme, a fluorescent template with a built-in azide group for photoaffinity labeling is also included as a part of the inhibitor design. Following incubation and irradiation, gel electrophoresis with visualization under UV allows assessment of the efficiency of cross-linking. The relative efficiency of cross-linking of various probes can be regarded as a reflection of their inhibition potencies, an assumption supported by the trend in their IC50/K i values. The method has the advantage of being applicable to impure enzyme preparations and also can be used to screen several inhibitors including their promiscuity in parallel in a short time as has been currently demonstrated with HCA II.

Abstract
Multicomponent reactions represent a highly efficient approach to a broad spectrum of structurally diverse compounds starting from simple and affordable compounds. A focused library of tweezers-like compounds is prepared by employing the multicomponent Passerini reaction comprising enediyne-derived amino aldehydes. The reaction proceeds under mild conditions yielding Passerini products in good to excellent yields. Postcondensation modifications of Passerini products are demonstrated through a simple deprotection/coupling approach comprising amino functionality, furnishing enediyne cores with highly decorated arms.
