- Identification of N-Benzyl 3,5-Dinitrobenzamides Derived from PBTZ169 as Antitubercular Agents
-
A series of benzamide scaffolds were designed and synthesized by the thiazinone ring opening of PBTZ169, and N-benzyl 3,5-dinitrobenzamides were finally identified as anti-TB agents in this work. 3,5-Dinitrobenzamides D5, 6, 7, and 12 exhibit excellent in vitro activity against the drug susceptive Mycobacterium tuberculosis H37Rv strain (MIC: 0.0625 μg/mL) and two clinically isolated multidrug-resistant strains (MIC 0.016-0.125 μg/mL). Compound D6 displays acceptable safety and better pharmacokinetic profiles than PBTZ169, suggesting its promising potential to be a lead compound for future antitubercular drug discovery.

- THERAPEUTIC MACROLIDE COMPOUNDS AND THEIR USE
-
The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain macrolide compounds (for convenience, collectively referred to herein as "MC compounds"), which, inter alia, are useful in treatment of cancer. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to treat proliferative conditions such as cancer, and in the treatment of diseases and conditions that are mediated by the regulation (e.g. inhibition) of cell proliferation, optionally in combination with another agent.

- Potent inhibitors of tRNA-guanine transglycosylase, an enzyme linked to the pathogenicity of the Shigella bacterium: Charge-assisted hydrogen bonding
-
Improving inhibition: tRNA-Guanine transglycosylase (TGT) is a newly recognized target to reduce the pathogenicity of disease-causing Shigella bacteria. A potent family of inhibitors of this enzyme has been developed by structure-based design. Crystallographic data and pKa, analysis suggest that the aminoimidazole moiety of the central lin-benzoguanine scaffold is protonated and stabilization of the complexes results from charge-assisted hydrogen bonding. (Figure Presented).

- In vitro structure-activity relationship and in vivo characterization of 1-(aryl)-3-(4-(amino)benzyl)urea transient receptor potential vanilloid 1 antagonists
-
The synthesis and structure-activity relationship of 1-(aryl)-3-(4-(amino) benzyl)urea transient receptor potential vanilloid 1 (TRPV1) antagonists are described. A variety of cyclic amine substituents are well tolerated at the 4-position of the benzyl group on compounds containing either an isoquinoline or indazole heterocyclic core. These compounds are potent antagonists of capsaicin activation of the TRPV1 receptor in vitro. Analogues, such as compound 45, have been identified that have good in vivo activity in animal models of pain. Further optimization of 45 resulted in compound 58 with substantially improved microsome stability and oral bioavailability, as well as in vivo activity.

- Synthesis and evaluation of cyclic secondary amine substituted phenyl and benzyl nitrofuranyl amides as novel antituberculosis agents
-
In an ongoing effort to develop new and potent antituberculosis agents, a second-generation series of nitrofuranyl amides was synthesized on the basis of the lead compound 5-nitrofuran-2-carboxylic acid 3,4-dimethoxybenzylamide. The primary design consideration was to improve the solubility and consequently the bioavailability of the series by the addition of hydrophilic rings to the benzyl and phenyl B ring core. The synthesis of 27 cyclic, secondary amine substituted phenyl and benzyl nitrofuranyl amides is described and their activity against Mycobacterium tuberculosis reported. The series showed a strong structure-activity relationship as the benzyl nitrofuranyl amides were significantly more active than similarly substituted phenyl nitrofuranyl amides. Para-substituted benzyl piperazines showed the most antituberculosis activity. Compounds in the series were subsequently selected for bioavailability and in vivo testing. This study led to the successful discovery of novel compounds with increased antituberculosis activity in vitro and a better understanding of the requisite pharmacological properties to advance this class.
