To improve the drug-resistance profiles of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs), a novel series of “dual-site” binding diarylpyrimidine (DAPY) derivatives I [R1 = H, cyclopropyl, propargyl, etc.] and II [X = 1-R2-piperidin-4-yl, 1-R2-piperidin-4-ylmethyl, 1-R2-pyrrolidin-3-yl; R2 = methylsulfonyl, trifluoromethylsulfonyl, trifluoromethylcarbonyl, etc.] targeting both the NNRTI adjacent site and NNRTIs binding pocket (NNIBP) were designed, synthesized and evaluated for their anti-HIV potency in TZM-bl and MT-4 cells. Eight compounds I and II exhibited moderate to excellent potencies in inhibiting wild-type (WT) HIV-1 replication with EC50 values ranging from 2.45 nM to 5.36 nM, and I [R1 = propargylamino] (EC50 = 2.45 nM) proved to be the most promising inhibitor. Of note, I [R1 = propargylamino] exhibited potent activity against the single mutant strain E138K (EC50 = 10.6 nM), being comparable with ETR (EC50 = 9.80 nM) and 3.5-fold more potent than that of morpholino pyrimidine compound (EC50 = 37.3 nM). Moreover, I [R1 = propargylamino] acted as a classical NNRTI with high affinity for WT HIV-1 RT (IC50 = 0.0589μM). The detailed structure-activity relationships (SARs) of the representative compounds were also determined, and further supported by mol. dynamics simulation. Overall, the “dual-site”-binding NNRTIs have significant prospects and pave the way for the next round of rational design of potent anti-HIV-1 agents. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3HPLC of Formula: 109-85-3).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 109-85-3
