Structure-Based Design of 1-Heteroaryl-1,3-propanediamine Derivatives as a Novel Series of CC-Chemokine Receptor 5 Antagonists

CC-chemokine receptor 5 (CCR5) is an attractive target for preventing the entry of human immunodeficiency virus 1 (HIV-1) into human host cells. Maraviroc is the only CCR5 antagonist, and it was marketed in 2007. To overcome the shortcomings of maraviroc, structure-based drug design was performed to minimize CYP450 inhibition and to enhance anti-HIV potency and bioavailability. Thirty-four novel 1-heteroaryl-1,3-propanediamine derivatives (1-34) were synthesized, displaying CCR5-antagonist activities in the 2.3-296.4 nM range. Among these, compounds 21 and 34 were the most potent CCR5 antagonists, with excellent in vitro anti-HIV-1 activity, low cytotoxicity, and an acceptable pharmacokinetic profile. Furthermore, the X-ray crystal structures of compounds 21 and 34 bound to CCR5 were determined at 2.8 A resolution. Compound 34 exhibited no CYP450-inhibition activity at 25 muM, which overcomes the potential drug-drug interaction of maraviroc. Compound 34 represents a promising drug candidate for HIV-infection treatment.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 3364-80-5, you can also check out more blogs about3364-80-5

A Mechanism for the Photosubstitution of Fluoro- and Methoxy-benzenes by Diethylamine

The photochemical reactions of fluoro- and methoxy-benzenes with diethylamine produce addition and substitution products.The proposed mechanism involves quenching of the singlet state by the amine to give an exciplex.Proton transfer within the exciplex leads to the amine adducts, some of which can undergo elimination to yield the substitution products.

3,6-Disubstituted carbazole chromophores containing thiazole and benzothiazole units: Synthesis, characterization and first-order hyperpolarizabilities

3,6-Disubstituted carbazole chromophores containing thiazole and benzothiazole units were synthesized and characterized by NMR, IR, and UV. The first-order hyperpolarizabilities (beta) were calculated via solvatochromic method. Our experiments suggest that the incorporation of thiazole and benzothiazole into carbazole-based chromophores can allow for significant enhancement of molecular hyperpolarizabilities. Nonlinear optical properties of ApiDpiA carbazole chromophores are superior to those of the corresponding DpiA aryl compounds.

Discovery of novel DNA gyrase B inhibitors remains an attractive field in the search for new antibacterial drugs to overcome the known bacterial resistance mechanisms. In the present study, we designed and synthesized novel ethylurea derivatives of 4,5,6,7-tetrahydrobenzo[1,2-d]thiazole-2,6-diamine, 2-(2-aminothiazol-4-yl)acetic acid, and benzo[1,2-d]thiazole-2,6-diamine and evaluated their Escherichia coli DNA gyrase inhibition. The most potent DNA gyrase inhibitors in the prepared library of compounds were benzo[1,2-d]thiazoles 32?34, 36, and 37 with IC50 values in the low micromolar range. The most promising inhibitors identified were evaluated against selected Gram-positive and Gram-negative bacterial strains. Compound 33 showed a MIC of 50 muM against an E. coli efflux pump-defective strain, which suggests that efflux decreases the on-target concentrations of these compounds.

Retinoids exert their biological effects by binding to and activating nuclear receptors that interact with responsive elements on DNA to promote gene transcription. There are two families of retinoid receptors, the retinoic acid receptor (RAR) family and the retinoid X receptor (RXR) family, which are each further divided into three subclasses: RAR(alpha,beta,gamma) and RXR(alpha,beta,gamma). Herein we describe the synthesis and structure-activity relationships of a new series of diaryl sulfide retinoid analogs that specifically bind and transactivate the RXRs. Furthermore, the sulfoxide and sulfone derivatives of these analogs are partial agonists which activate the RXRs only at high concentrations. Thus, these compounds possess a potential site of metabolic deactivation and may have less prolonged systemic effects than other compounds with arotinoid-like structures. We show also that these compounds have activity in nontransfected cells as demonstrated by their ability to induce TGase activity in HL-60 cells. Finally, we corroborate our earlier report that RXR-specific agonists may possess reduced teratogenic toxicity compared to RAR-specific agonists since these compounds are much less potent inhibitors of chondrogenesis than RAR-specific agonists such as TTNPB.
