A series of novel triazole derivatives containing γ-lactam I [R = Br, 5-pyrimidinyl, Ph, etc.] was designed and synthesized, and their structures were confirmed by 1H NMR, 13C NMR and HRMS. The in vitro antifungal activities of the target compounds were evaluated. The results showed that all of the compounds exhibited stronger activity against the six clin. important fungi tested than fluconazole. Compounds I [R = 3-cyano-6-pyridinyl, 4-fluorophenyl] showed comparative activity against the fungi tested except for Candida glabrata and Aspergillus fumigatus as voriconazole. In addition, the docking model for 2-bromo-5-((2R,3R)-3-(2,4-difluorophenyl)-3-hydroxy-4-(1H-1,2,4-triazol-1-yl)butan-2-yl)-5,6-dihydro-4H-pyrrolo[3,4-d]thiazol-4-one and CYP51 was investigated.

Zhang, Kuojun; Yao, Yiwu; Tu, Zhengchao; Liao, Chenzhong; Wang, Zhen; Qiu, Yatao; Chen, Dong; Hamilton, Dale J.; Li, Zheng; Jiang, Sheng published the artcile< Discovery of class I histone deacetylase inhibitors based on romidpesin with promising selectivity for cancer cells>, Recommanded Product: Ethyl 2-(((tert-butoxycarbonyl)amino)methyl)thiazole-4-carboxylate, the main research area is romidpesin class I histone deacetylase inhibitor cancer cell selectivity; antitumor; class I histone deacetylases; cyclic depsipeptides; inhibitor; structure–activity relationship.

Aim: Class I histone deacetylases (HDACs) are considered to be promising anticancer targets, but selective inhibition of class I HDAC isoforms remains a challenge. Methods & results: Previously, we obtained a selective class I HDAC inhibitor 9 based on a macrocyclic HDAC inhibitor Romidpesin. As our continuous efforts, a library of novel cyclicdepsipeptides based on 9 was established using a convergent synthesis strategy. The most active compounds 10, 16 and 19 selectively inhibit class I HDACs and exhibit promising nanomolar antiproliferative activities against several cancer cell lines with excellent selectivity toward cancer cells over normal cells. Besides, compound 10 demonstrates excellent antitumor effects in human prostate carcinoma PC3 xenograft models with no observed toxicity. Conclusion: These cyclicdepsipeptides show great therapeutic potential as novel anticancer agents for clin. translation.

Akbarzadeh, Elaheh; Shockravi, Abbas; Vatanpour, Vahid published the artcile< Efficient thiazole-based polyimines as selective and reversible chemical absorbents for CO2 capture and separation: Synthesis, characterization and application>, Computed Properties of 57493-24-0, the main research area is thiazole thioether polyimine chem absorbent carbon dioxide capture separation.

A new series of polyimines (PIMs-1-9) including ortho-linked thiazole units and flexible thioether linkages were synthesized from diamine monomers (DA-1-3) and some com. available aromatic dialdehydes (terephthalaldehyde, isophthalaldehyde and 2,5-thiophenedicarboxaldehyde) via Schiff-base condensation reaction. The synthesized polymers as amorphous solids were obtained with high efficiency (74-89%), inherent viscosities in the range of 0.98-1.33 dL g-1 in DMF and high solubility in aprotic polar solvents (DMSO, DMAc, DMF, NMP, and Py). The PIMs were characterized via viscosimetry, elemental anal., FT-IR spectroscopy, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC). High thermal resistance revealed for PIMs as glass transition temperatures (Tgs) ranging in 104-189 °C along with 10% weight loss temperatures exceeding 268-390 °C in air and 310-430 °C in nitrogen atm. The polymers were examined for CO2 absorption at 298 K as well as 318 K and high absorption capacity exhibited (maximum 3.72 mmol/g or 163.68 mg/g at 1 bar and 298 K for PIM-4) after 2 h and desorption at 373 K under vacuum conditions (100 mbar) in 20 min. More importantly, remarkable ideal selectivity ratios of CO2/N2 (77.3) and CO2/CH4 (13.7) at 1 bar and 298 K were obtained and recyclability of PIM-4 for CO2 capturing was determined without considerable loss of gas absorption.

Lefeuvre, Bastien; Cantero, Paola; Ehret-Sabatier, Laurence; Lenormand, Cedric; Barthel, Cathy; Po, Chrystelle; Parveen, Nikhat; Grillon, Antoine; Jaulhac, Benoit; Boulanger, Nathalie published the artcile< Effects of topical corticosteroids and lidocaine on Borrelia burgdorferi sensu lato in mouse skin: potential impact to human clinical trials>, Related Products of 2591-17-5, the main research area is Borrelia skin topical corticosteroid lidocaine.

Abstract: Lyme borreliosis is the most prevalent vector-borne disease in northern hemisphere. However, in patients presenting persistent clin. manifestations, this indirect diagnosis is not capable of detecting an active infection. If the serol. tests are pos., it only proves that exposure of an individual to Lyme spirochetes had occurred. Although culture and quant. PCR detect active infection, currently used tests are not sensitive enough for wide-ranging applications. Animal models have shown that B. burgdorferi persists in the skin. We present here our targeted proteomics results using infected mouse skin biopsies that facilitate detection of this pathogen. We have employed several novel approaches in this study. First, the effect of lidocaine, a local anesthetic used for human skin biopsy, on B. burgdorferi presence was measured. We further determined the impact of topical corticosteroids to reactivate Borrelia locally in the skin. This local immunosuppressive compound helps follow-up detection of spirochetes by proteomic anal. of Borrelia present in the skin. This approach could be developed as a novel diagnostic test for active Lyme borreliosis in patients presenting disseminated persistent infection. Although our results using topical corticosteroids in mice are highly promising for recovery of spirochetes, further optimization will be needed to translate this strategy for diagnosis of Lyme disease in patients.

Yao, Zi; Zhang, Brendan S.; Steinhardt, Rachel C.; Mills, Jeremy H.; Prescher, Jennifer A. published the artcile< Multicomponent Bioluminescence Imaging with a π-Extended Luciferin>, COA of Formula: C11H8N2O3S2, the main research area is multicomponent bioluminescence imaging luciferin.

Bioluminescence imaging with luciferase-luciferin pairs is commonly used for monitoring biol. processes in cells and whole organisms. Traditional bioluminescent probes are limited in scope, though, as they cannot be easily distinguished in biol. environments, precluding efforts to visualize multicellular processes. Addnl., many luciferase-luciferin pairs emit light that is poorly tissue penetrant, hindering efforts to visualize targets in deep tissues. To address these issues, the authors synthesized a set of π-extended luciferins that were predicted to be red shifted luminophores. The scaffolds were designed to be rotationally labile such that they produced light only when paired with luciferases capable of enforcing planarity. A luciferin comprising an intramol. “”lock”” was identified as a viable light-emitting probe. Native luciferases were unable to efficiently process the analog, but a complementary luciferase was identified via Rosetta-guided enzyme design. The unique enzyme-substrate pair is red shifted compared to known bioluminescent tools. The probe set is also orthogonal to other luciferase-luciferin probes and can be used for multicomponent imaging. Four substrate-resolved luciferases were imaged in a single session. Collectively, this work provides the first example of Rosetta-guided design in engineering bioluminescent tools and expands the scope of orthogonal imaging probes.
