Considering the fact that tryptophan (W) and histidine are residues similar in size, we hypothesized that S375H might contribute to BMS-599793 resistance by filling the gp120 CD4 binding cavity. Figuring out the frequency of mutation at Env amino acid 375 among distinct subtypes. To assess the clinical relevance of mutations at title= ejhg.2011.98 Env position 375, 1,668 sequences from HIV-1 subtypes A to D and CRF01_AE (from the Los Alamos HIV sequence database) were analyzed for amino acid variation at the 375 place. The results indicated that subtypes A to D most often coded for S375 (84.1 for subtype A, 72.4 for subtype B, 95.8 for subtype C, and 87.four for subtype D), with several degrees ofaac.asm.orgAntimicrobial Agents and ChemotherapyImportance of an H375 Polymorphism in HIV-1 envTABLE 1 BMS-599793 EC50s, EC75s, and EC90s needed to inhibit genetically divergent HIVBMS-599793 EC (nM) Subtype A A B B B B C C C C C D title= ajpcell.00040.2011 D AE AE AE AE AE AE AG A Aa bCoreceptor tropism CCR5 CCR5 CXCR4 CCR5 CCR5 CCR5 CCR5 CCR5 CCR5 CCR5 CCR5 CCR5 CCR5 CXCR4 CXCR4/CCR5 CCR5 CXCR4 CXCR4 CXCR4/CCR5 CCR5 CXCR4 CXCRHIV-1 virusdHIV-2 virus50 a 19.50 0.0908 3.899 0.1781 0.354 0.0548 1.43 0.0211 0.399 0.0467 0.01181 0.2599 0.130 0.0603 0.0164 0.0812 0.300 0.0870 24.6 0.284 23.2 0.117 1.057 0.2888 0.003119 0.5763 363 1.19 273 two.40 251 0.615 two,223 0.115 7,349 0.02154 5,470 0.02368 0.101 0.0313 10,000c 10,75 64.8 0.107 56.91 0.2605 0.656 0.0722 2.22 0.0453 1.19 0.126 0.3649 0.3812 0.265 0.101 0.0442 0.0473 1.12 0.123 144 0.514 76.4 0.200 four.864 0.4372 0.02506 0.3729 1,814 0.574 1,469 1.03 719 0.328 four,087 0.190 8,727 0.04071 7,379 0.03707 0.6931 0.9212 ten,000 ten,90 216 0.171 830.six 0.4839 1.22 0.107 3.47 0.0708 3.31 0.192 11.28 0.6324 0.538 0.159 NC ( 1)b 4.18 0.201 842 0.790 251 0.301 22.37 0.7223 0.2013 0.2187 9,069 1.255 7,904 1.71 2,055 0.366 7,515 0.295 ten,364 0.05989 9,953 0.05717 four.498 1.433 ten,000 10,6050 92UG037 NL4-3* NL(AD8)* Ba-L* 5512 INDIE-C1* MJ4* MOLE1 MOLE3 MOLE13 6030 94UG114 6240 6343 92TH001 CMU06 NI1052 NP1525 97GH-AG1* MVP CBL- 20/HMean concentration from 3 independent experiments log(SE) at ECs indicated for each HIV-1 tested.
