spp. includes opportunistic pathogens that are responsible for superficial and invasive infections. These strains have mechanisms of resistance against antimicrobials. Riparin compounds isolated from the green fruit of the plant (Nees) Mez, are alkaloids with alkamide function with notable antimicrobial properties. We evaluated the inhibitory effect () of Riparins isolated and combined with Fluconazole
种。包括导致浅表和侵袭性感染的机会病原体。这些菌株具有抗微生物药物的耐药机制。从植物 (Nees) Mez 的绿色果实中分离出的 Riparin 化合物是具有烷酰胺功能的生物碱,具有显着的抗菌特性。我们评估了分离的 Riparins 并与氟康唑联合使用对 、 和 菌株的抑制效果 ();在测试中,MdR1、CdR1 和 CdR2 因子的抗活性。通过 1H NMR 光谱(1H 和 13C)、电喷雾电离质谱 (ESI-MS) 鉴定 Riparins,并与之前报道的光谱数据进行比较。对于抗真菌活性曲线,使用肉汤微量稀释技术(1-1024μg/mL)。对于组合抗真菌活性,Riparins 在固定亚抑制浓度(RI、RII 和 RIV 为 256 µg/mL,RIII 为 64 µg/mL)和 FCZ(范围为 1 至 1024 µg/mL)进行测试。最低杀菌剂浓度通过培养皿中的微培养进行。用于分子对接,
