Abstract To address the intractable issues of drug resistance and poor solubility, a novel series of morpholine-substituted diarylpyrimidines targeting the tolerant region I and tolerant region II of NNIBP were rationally designed by utilizing the available crystallography studies. The biological evaluation results showed that four most promising compounds (14e1, 14g1, 14g2 and 14j2) displayed excellent potency against WT HIV-1 strain with EC(50) values ranging from 58 to 87 nM, being far more potent than NVP and comparable to ETV. Besides, some derivatives exhibited moderate activity in inhibiting the mutant HIV-1 strains. More encouragingly, 14d2 (RF = 0.4) possessed higher antiresistance profile than ETV (RF = 6.3) and K-5a2 (RF = 3.0) toward the double mutant strain F227L + V106A. The HIV-1 RT inhibition assay confirmed their binding target. The molecular docking studies were conducted and discussed in detail to rationalize the preliminary SARs. Further test indicated that morpholine could indeed promote the improvement of water solubility. Additionally, the in silico prediction of physicochemical properties and CYP enzymatic inhibitory ability were investigated to evaluate their drug-like features.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
