A series of new bis derivatives of 2,5-thiadiazole and N,N′-thiocarbohydrazide along with their transition metal complexes were synthesized by green methods (sonochemical and microwave), i.e., energy and time efficient and operationally more simple than existing conventional methods. All the synthesized compounds were fully characterized by routine analytical techniques and subjected to a preliminary biological screening. These novel characterized compounds were screened for antimicrobial activities and showed promising results. A few potent compounds were also tested for antitumor activities against MDA-MB231 (human breast carcinoma cell line) and compound 5 has emerged as a potential antitumor compound followed by compound 2, 10 and 9, with IC50 values of 29.48, 32.25, 32.34 and 34.34 μg/ml, respectively. To understand the binding interactions of these compounds, in silico studies were performed using the AUTODOCK 4.2 suite and found to be supportive of the experimental results.
