A new class of Chalcone-Sulphonamide hybrids has been designed by condensing appropriate sulphonamide scaffold with substituted chalcones tethered by chloroacetyl chloride as a multi-target drug for therapeutic treatment. Chalcones were prepared by Claisen-Schmidt condensation of a substituted aldehyde with para aminoacetophenone. These Chalcone-Sulphonamide hybrids were screened by means of their antibacterial activity by NCCLS method. Among all these compounds, 5e and 5c displayed more potent growth inhibitory activity against Staphylococcus epidermidis and Pseudomonas aeruginosa bacteria respectively. Further, these hybrids were evaluated for their antifungal activity, among all hybrid 5a exhibited potent antifungal activity. The synthesized compounds were characterized by FT-IR, $^1HNMR$, $^13}CNMR$ and HR-LCMS and spectral study supports the structures of synthesized Chalcone-Sulphonamide hybrids.
通过将适当的磺酰胺支架与氯乙酰氯拴住的取代查耳酮缩合,设计出了一类新的查耳酮-磺酰胺杂交化合物,作为多靶点治疗药物。查耳酮是通过取代醛与对氨基苯乙酮的克莱森-施密特缩合反应制备的。通过 NCCLS 方法对这些查耳酮-磺酰胺杂化物的抗菌活性进行了筛选。在所有这些化合物中,5e 和 5c 分别对表皮葡萄球菌和绿脓杆菌具有更强的生长抑制活性。此外,还对这些杂交化合物的抗真菌活性进行了评估,其中杂交化合物 5a 具有很强的抗真菌活性。通过傅立叶变换红外光谱(FT-IR)、$^1HNMR$、$^13}CNMR$和 HR-LCMS,对合成的化合物进行了表征。
