overexpressing the GlcN-6-P synthase enzyme are tested to demonstrate the immediate inhibitory effects of nanoparticle conjugates against mammalian cells. It is shown that nanoparticle-mediated delivery transforms FMDP and BADP into strong anticancer agents by inhibiting the growth of the tested cancer cells, whereas their anti-Candidal activity is decreased. This study discusses the emerging inhibitory effect
在过去的3.5年中,已有许多谷氨酰胺类似物被报告为致病性白色念珠菌中6-磷酸氨基葡萄糖(GlcN-6-P)合酶的不可逆抑制剂。中所报道的抑制剂,最有效的Ñ 3 - (4- methoxyfumaroyl) -升-2,3-二氨基丙酸(FMDP)已被广泛研究,以开发其更具活性的类似物。测试了几种肽-FMDP偶联物,可将FMDP递送至位于亚细胞中的GlcN-6-P合酶靶标。但是,真菌对FMDP肽的耐药性迅速发展,需要开发不同的治疗方法来应对抗真菌性耐药。在目前的全球抗真菌抗药性的状态下,通过自由扩散或内吞作用向FMDP的亚细胞递送已变得至关重要。在这项研究中,我们在和它的类似物酮酸之一,FMDP的体外nanomedical应用报告Ñ 3 -反式-4-氧代-4-苯基-2- butenoyl-升-2,3-二氨基丙酸(BADP)。FMDP和BADP共价结合到聚乙二醇涂层的氧化铁/二氧化硅核-壳纳米粒子
