Multidrug resistance is a paramount impediment to successful treatment of most hospital acquired bacterial infections. A plethora of bacterial genera exhibit differential levels of resistance to the existing antibiotics. Prevalent Uropathogenic Escherichia coli or UPEC conduce high mortality among them. Multi-Drug Resistant bacterial strains utilize precise mechanisms to bypass effects of antibiotics. This is probably due to their familiar genomic origin. In this article drug repositioning method have been utilised to target 23 enzymes of UPEC strains viz. CFT073, 536 and UTI89. 3-D drug binding motifs have been predicted using SPRITE and ASSAM servers that compare amino acid side chain similarities. From the hit results anti-viral drugs have been considered for their uniqueness and specificity. Out of 14 anti-viral drugs 3 anti-HIV drugs viz. Amprenavir, Darunavir and Saquinavir have selected for maximum binding score or drug targetability. Finally, active sites of the enzymes were analyzed using GASS-WEB for eloquent drug interference. Further analyses with the active sites of all the enzymes showed that the three selected anti-HIV drugs were very much potent to inhibit their active sites. Combination or sole application of Amprenavir, Darunavir and Saquinavir to MDR-UPEC infections may leads to cure and inhibition of mortality.

多重耐药性是成功治疗大多数医院获得性细菌感染的首要障碍。大量细菌属对现有抗生素表现出不同程度的耐药性。常见的尿路致病性大肠杆菌(UPEC)在其中导致高死亡率。多重耐药细菌菌株利用精确机制绕过抗生素的作用。这可能归因于它们相似的基因组起源。在本文中,采用药物重新定位方法针对UPEC菌株(即CFT073、536和UTI89)的23种酶。使用SPRITE和ASSAM服务器预测了三维药物结合基序,这些服务器比较氨基酸侧链相似性。从命中结果中,考虑了抗病毒药物的独特性和特异性。在14种抗病毒药物中,3种抗HIV药物(即安普那韦、达芦那韦和沙奎那韦)因最大结合分数或药物靶向性而被选中。最后,使用GASS-WEB分析酶的活性位点以进行有效的药物干扰。对所有酶的活性位点的进一步分析表明,所选的三种抗HIV药物非常有效地抑制了它们的活性位点。将安普那韦、达芦那韦和沙奎那韦联合或单独应用于多重耐药UPEC感染可能会治愈并抑制死亡率。
