synthesis of eight different N-alkylated pyridine-based organic salts QAS 1–8 and their antibacterial, antibiofilm and wound healing activities. 3-(2-R-hydrazinecarbonyl)-1-propylpyridinium Bromide was the parent compound while R group was varying in each salt composed of different aromatic aldehyde moieties. In the antibacterial activity against S. aureus and E. coli, amoxicillin shows IC50 near to
在治疗伤口中,长期感染被认为是主要障碍。病原微生物通过抗生素耐药性使药物无效,并呼吁设计和开发新药物。此,我们报告的八个不同的合成Ñ烷基化吡啶系有机盐QAS 1 - 8和它们的抗菌,抗生物膜和伤口愈合的活动。溴化物3-(2-R-肼羰基)-1-丙基吡啶是母体化合物,而由不同芳族醛基部分组成的每种盐中的R基团均不同。在对金黄色葡萄球菌和大肠杆菌的抗菌活性中,阿莫西林显示IC 50接近25 µg / mL,抑制58±0.4%金黄色葡萄球菌同时头孢曲松抑制浓度为10 µg / mL的55±0.5%大肠杆菌。化合物QAS 7在100 µg / mL的浓度下显示出最高的IC 50(对金黄色葡萄球菌为56±0.5%;对大肠杆菌为55±0.5%)。其次是QAS 6(对大肠杆菌为55±0.5%)和QAS 2(对大肠杆菌为55±0.5%)。在抗生物膜活性方面,QAS 6,QAS 1和QAS 8在浓度为75 µg
