Abstract

One of the major problems in the fight against cancer is drug-resistance, which, at a molecular level, can be acquired through mutations able to deactivate apoptosis. In particular, proteins in the Bcl-2 family are central regulators of programmed cell death, and members that inhibit apoptosis, such as Bcl-xl and Bcl-2, are overexpressed in many tumours. The development of new inhibitors of these proteins as potential anticancer therapeutics represents a new frontier. In this work, we carried out an in-silico screening of compounds from a free database of more than 2 million structures (ZINC database), which allowed us to identify 17 sulfonamide derivatives as new potential inhibitors; these are currently undergoing biological evaluation.
