Feng, Da; Wei, Fenju; Sun, Yanying; Sharma, Prem Prakash; Zhang, Tao; Lin, Hao; Rathi, Brijesh; De Clercq, Erik; Pannecouque, Christophe; Kang, Dongwei; Zhan, Peng; Liu, Xinyong published the artcile< Boronic acid-containing diarylpyrimidine derivatives as novel HIV-1 NNRTIs: Design, synthesis and biological evaluation>, HPLC of Formula: 18740-39-1, the main research area is boronic acid diarylpyrimidine preparation human immunodeficiency virus 1 inhibitor; acid boronic diarylpyrimidine preparation HIV1 nonnucleoside reverse transcriptase inhibitor; mol dynamics simulation boronic acid diarylpyrimidine HIV 1 inhibitor.

Drug resistance remains to be a serious problem with type I human immunodeficiency virus (HIV-1) non-nucleoside reverse transcriptase inhibitors (NNRTIs). A series of novel boronic acid-containing diarylpyrimidine (DAPY) derivatives were designed via bioisosterism and scaffold-hopping strategies, taking advantage of the ability of a boronic acid group to form multiple hydrogen bonds. The target compounds were synthesized and evaluated for their anti-HIV activities and cytotoxicity in MT-4 cells. Compound 10j yielded the most potent activity and turned out to be a single-digit nanomolar inhibitor towards the HIV-1 IIIB [wild-type (WT) strain], L100I and K103N strains, with 50% effective concentration (EC50) values of 7.19-9.85 nmol/L. Moreover, 10j inhibited the double-mutant strain RES056 with an EC50 value of 77.9 nmol/L, which was 3.3-more potent than that of EFV (EC50 = 260 nmol/L) and comparable to that of ETR (EC50 = 32.2 nmol/L). 10J acted like classical NNRTIs with high affinity for WT HIV-1 reverse transcriptase (RT) with 50% inhibition concentration (IC50) value of 0.1837μmol/L. Furthermore, mol. dynamics simulation indicated that 10j was proposed as a promising mol. for fighting against HIV-1 infection through inhibiting RT activity. Overall, the results demonstrated that 10j could serve as a lead mol. for further modification to address virus-drug resistance.

Several new thieno[2,3-d]pyrimidine derivatives 3-substituted phenyl-5-(thiophen-2-yl)thieno[3,2-e] [1,2,4]triazolo[4,3-c]pyrimidines I [R = Ph, 3-pyridyl, 1H-indol-2-yl, etc.] were synthesized starting from thieno[2,3-d]pyrimidine-2,4-diol. The characterization of the newly synthesized compounds I was established by IR, 1H NMR, 13C NMR and mass spectral anal. The final compounds I were screened for their antibacterial activity against Bacillus subtilis and Staphylococcus aureus from Gram pos. group of bacteria and Escherichia coli and Klebsiella pneumonia from Gram neg. group of bacteria and antifungal activity against Candida albicans and Aspergillus flavus. Antibacterial and antifungal activities were evaluated and compared with the standard drugs. From antibacterial and antifungal activity screening results, it was observed that compounds I [R = 3-pyridyl, 1H-indol-2-yl, 4-F3CC6H5] possessed good activity.

By repurposing a typical dopamine D1/D5 receptor agonist motif, C1-substituted-N3-benzazepine or benzazecine, into the classical RTK inhibitor 2,4-diaminopyrimidine skeleton, a series of new 2,4-diarylaminopyrimidine analogs (DAAPalogues) were developed. Two compounds were identified possessing high potency against both c-Met and ALK kinases. Compound (I) displayed appreciable antitumor efficacy at the dose of 1 mg/kg in the ALK-driven BF3/EML4-ALK xenograft mice model.

Odingo, Joshua; O’Malley, Theresa; Kesicki, Edward A.; Alling, Torey; Bailey, Mai Ann; Early, Julie; Ollinger, Juliane; Dalai, Suryakanta; Kumar, Naresh; Singh, Ravindra Vikram; Hipskind, Philip A.; Cramer, Jeffrey W.; Ioerger, Thomas; Sacchettini, James; Vickers, Richard; Parish, Tanya published the artcile< Synthesis and evaluation of the 2,4-diaminoquinazoline series as anti-tubercular agents>, COA of Formula: C6H2Cl2N2S, the main research area is diaminoquinazoline preparation tuberculostatic Mycobacterium tuberculosis; 2,4-Diaminoquinazoline; Antibacterial activity; Dioxygenase; Mycobacterium tuberculosis; Tuberculosis.

The 2,4-diaminoquinazoline class of compounds has previously been identified as an effective inhibitor of Mycobacterium tuberculosis growth. The authors conducted an extensive evaluation of the series for its potential as a lead candidate for tuberculosis drug discovery. Three segments of the representative mol. N-(4-fluorobenzyl)-2-(piperidin-1-yl)quinazolin-4-amine were examined systematically to explore structure-activity relationships influencing potency. The authors determined that the benzylic amine at the 4-position, the piperidine at 2-position and the N-1 (but not N-3) are key activity determinants. The 3-deaza analog retained similar activity to the parent mol. Biol. activity was not dependent on iron or carbon source availability. The authors demonstrated through pharmacokinetic studies in rats that good in vivo compound exposure is achievable. A representative compound demonstrated bactericidal activity against both replicating and nonreplicating M. tuberculosis. The authors isolated and sequenced M. tuberculosis mutants resistant to this compound and observed mutations in Rv3161c, a gene predicted to encode a dioxygenase, suggesting that the compound may act as a prodrug.

Srimongkolpithak, Nitipol; Sundriyal, Sandeep; Li, Fengling; Vedadi, Masoud; Fuchter, Matthew J. published the artcile< Identification of 2,4-diamino-6,7-dimethoxyquinoline derivatives as G9a inhibitors>, Quality Control of 18740-39-1, the main research area is diamino dimethoxyquinoline derivative histone lysine methyltransferase inhibitor identification.

G9a is a histone lysine methyltransferase (HKMT) involved in epigenetic regulation via the installation of histone methylation marks. 6,7-Dimethoxyquinazoline analogs, such as BIX-01294, are established as potent, substrate competitive inhibitors of G9a. With an objective to identify novel chemotypes for substrate competitive inhibitors of G9a, we have designed and synthesized a range of heterocyclic scaffolds, and investigated their ability to inhibit G9a. These studies have led to improved understanding of the key pharmacophoric features of BIX-01294 and the identification of a new core quinoline inhibitory scaffold, which retains excellent potency and high selectivity. Mol. docking was carried out to explain the observed in vitro data.
