Optimization of 2-(1H-imidazo-2-yl)piperazines series of Trypanosoma brucei growth inhibitors as potential treatment for the second stage of HAT

A previous publication from our laboratory reported the identification of a new class of 2-(1H-imidazo-2-yl) piperazines as potent T. brucei growth inhibitors as potential treatment for Human African Trypanosomiasis (HAT). This work describes the structure-activity relationship (SAR) around the hit compound 1, which led to the identification of the optimized compound 18, a single digit nanomolar inhibitor (EC50, 7 nM), not cytotoxic and with optimal in vivo profile that made it a suitable candidate for efficacy studies in a mouse model mimicking the second stage of disease.

Molecular Insight into the Discrepancy of Antitubercular Activity between 8-Nitro and 8-Cyano Benzothiazinones

Benzothiazinones with 8-NO2 group is a novel class of compounds with potent antitubercular activity, especially BTZ043 and PBTZ169, which covalently inhibit DprE1. 8-CN benzothiazinones is reported as another type of benzothiazinones with potent antitubercular activity. Taking this as the starting point, a series of 8-CN benzothiazinones are synthesized and evaluated for their antitubercular activity. To better understand the antitubercular activity of this series of benzothiazinones, the difference between the molecular structures of CN01 and PBTZ169 in crystal are analyzed. CN01 and PBTZ169 show completely different conformations of the piperazine ring. Density functional theory analysis (DFT) and molecular dynamics (MD) simulation are performed to provide more details to explain the different antitubercular activity. All the analysis based on crystallography, quantum chemistry, and molecular modeling lay a foundation for the subsequent structural optimization of 8-CN benzothiazinones.

Performance enhancement of nanofiltration membranes via surface modification with a novel acylation reagent

Acyl chloride monomers have been serving as the dominant acylation reagent for preparing thin-film composite (TFC) nanofiltration (NF) membranes over the past few decades. Herein, a novel acylation reagent (trimellitic anhydride, TMA) was exploited in conjunction with trimesoyl chloride (TMC) to undergo interfacial polymerization with piperazine (PIP) on the polysulfone substrate membranes. The introduction of TMA enabled the deeper diffusion of PIP monomers into the organic phase, resulting in the creation of novel circular-shaped protuberances on the top surface of the polyamide layer and the significant increase in the effective membrane area. Besides, abundant in-situ carboxylic groups were generated in the polyamide layer, conducive to both the surface hydrophilicity and negative charge density. Consequently, with an addition of 0.03 wt% TMA, pure water flux reached up to 15.3 L m(-2) hour(-1) bar(-1), almost 2.2 times that of the pristine membrane, and high rejection of Na2SO4 (97.3%) was maintained, evincing the superior desalination performance of the TMA-modified membranes. The interaction mechanism between TMA, TMC, and PIP was described in detail. Furthermore, the TMA-modified membranes exhibited a stable separation performance over the long-running process.

Synthesis and anthelmintic activity of some novel (E)-2-methyl/propyl-4-(2-(substitutedbenzylidene)hydrazinyl)-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidines

A series of some novel (E)-2-methyl/propyl-4-[(2-(substitutedbenzylidene)hydrazinyl]-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidines was synthesized and characterized by adopting an appropriate synthetic scheme. The effect of electron withdrawing and electron donating groups at the aromatic ring in presence of methyl and propyl substituents at the 2-position of the scaffold was evaluated for anthelmintic activity against adult Indian earthworms (Pheretima posthuma). Among 2-methyl-thieno[2,3-d]pyrimidine analogs, compounds with electron donating methoxy group either atpara-position or atmetaandpara-positions of the aromatic ring showed potent anthelmintic activity at 100 mu g/ml (284 and 261.8 mu M concentrations) for compounds5gand5hwith a mean paralytic time of 2.32, 2.22 min, and helminthicidal time of 22.38, 19.43 min, respectively. In contrast, the presence of electron withdrawing chloro group atorthoandpara-position of the aromatic ring was found to be favorable for the anthelminthic activity of the compounds5nand5o(at concentration of 259.7 mu M) with propyl group at the 2-position of the thieno[2,3-d]pyrimidine scaffold, exhibiting mean paralytic time of 2.5 min, 2.81 min and helminthicidal time of 21, 20.03 min, respectively. Anthelmintic activities of these four compounds5g,5h,5n, and5o(at the concentrations of 284, 261.8, 259.7, and 259.7 mu M, respectively) were found to be on par with the standard drug piperazine adipate (time for paralysis and death at 6.25 and 24.5 min, respectively) at concentration of 100 mu g/ml (431.03 mu M). Overall, the potency of these compounds (5g,5h,5n, and5o) is better than standard drug as they exhibited the same activity at 259.7-284 mu M as that of a standard drug (which has shown the same activity at 431.03 mu M). Further, the predicted ADME properties of all the synthesized compounds were found to be in the satisfactory ranges as predicted by SwissADME software and found to have drug-like properties. Thus, further modification of these compounds might lead to the discovery of more potent analogs.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5308-25-8 is helpful to your research. Recommanded Product: 5308-25-8.
