Further clin. development of I, a lead compound targeting HIV-1 capsid, is impeded by low antiviral activity and inferior metabolic stability. By modifying the benzene (region I) and indole of I, we identified two potent compounds II [R = propargyl, 4-NH2Ph] with significantly improved metabolic stability. Compared to PF74, II [R = 4-NH2Ph] displayed greater metabolic stability in human liver microsomes (HLMs) with half-life (t1/2) 109-fold that of PF74. Moreover, mechanism of action (MOA) studies demonstrated that II [R = propargyl, 4-NH2Ph] effectively mirrored the MOA of compounds that interact within the I interprotomer pocket, showing direct and robust interactions with recombinant CA, and 7u displaying antiviral effects in both the early and late stages of HIV-1 replication. Furthermore, MD simulation corroborated that II [R = 4-NH2Ph] was bound to the I binding site, and the results of the online molinspiration software predicted that II [R = propargyl, 4-NH2Ph] had desirable physicochem. properties. Unexpectedly, this series of compounds exhibited better antiviral activity than I against HIV-2, represented by compound II [R = propargyl] whose anti-HIV-2 activity was almost 5 times increased potency over I. Therefore, we have rationally redesigned the I chemotype to inhibitors with novel structures and enhanced metabolic stability in this study. We hope that these new compounds can serve as a blueprint for developing a new generation of HIV treatment regimens. 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. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 109-85-3
