The possible efficacy of 1,3,4-oxadiazoles as B-cell lymphoma 2 (BCL-2) inhibitors for cancer treatment is investigated in this study using in silico approaches such as molecular docking, ADME and toxicity prediction. Molecular docking studies predict the binding affinities and binding modes of a series of 1,3,4-oxadiazole derivatives with the BCL-2 protein. The results revealed that the compounds with strong interactions and favourable binding modes, indicating their potential as BCL-2 inhibitors. An ADMET analysis assesses the pharmacokinetic properties and potential toxicity of the identified compounds. Parameters such as absorption, distribution, metabolism, excretion and toxicity (ADMET) were evaluated to predict the suitability of these 1,3,4-oxadiazoles as drug candidates for cancer therapy. The integration of molecular docking and ADMET analysis data led to the identification and prioritization of lead compounds with potent BCL-2 inhibitory activity and favourable pharmacokinetic profiles. This research contributes to the on-going efforts in drug discovery, emphasizing the potential of 1,3,4-oxadiazoles as a class of compounds with significant anticancer properties through BCL-2 inhibition.
