Degrasyn inhibits deubiquitination enzymes and has anti-cancer activity. We here show that it also exhibits antimicrobial activity against multi-resistant Staphylococcus aureus. Structure activity relationship studies demonstrate an important role of the electrophilic alpha-cyanoacrylamide moiety as a Michael acceptor. A suite of chemical proteomic techniques unraveled binding of this moiety to various cysteine residues of essential proteins in a reversibly covalent manner.

I found the field of Chemistry very interesting. Saw the article Highly efficient one-pot synthesis of alpha-aminophosphonates using nanoporous AlSBA-15 catalyst in a three-component system published in 2020.0. Name: 3-Pyridinecarboxaldehyde, Reprint Addresses Govindasamy, C (corresponding author), VIT Univ, Sch Adv Sci, Div Chem, Chennai 600127, Tamil Nadu, India.; Govindasamy, C (corresponding author), Imam Abdulrahman Bin Faisal Univ, IRMC, Dammam 31441, Saudi Arabia..

Nanoporous AlSBA-15 catalysts with different nSi/nAl ratios (41, 129, and 210) were synthesized using a hydrothermal method. These catalysts were characterized by XRD, N-2 sorption, TPD-NH3, FT-IR, SEM and TEM. XRD analyses of AlSBA-15 catalysts confirmed the presence of well-ordered crystalline structure with p6mm symmetry. The specific surface area and specific pore volume of the AlSBA-15 catalysts are in the range of 480 to 757 m(2)/g and 0.65 to 0.95 cm(3)/g, respectively. The catalytic performance of nanoporous AlSBA-15 catalysts are used as an outstanding catalytic system for one-pot synthesis of alpha-aminophosphonates via Kabachnik-Fields reaction in a three-component system using amines (primary/secondary), carbonyl compounds (aldehydes/ketones) and diethyl phosphite. The major advantages of the present contributions are excellent yields, short reaction time, simple experimental technique, high chemo-selectivity, catalyst recyclability, easy work-up procedure and green approach. Three-component synthesis of alpha-aminophosphonates follows first imine formation from amine and aldehyde/ketone followed by phosphate addition. The experimental findings suggest that the nanoporous AlSBA-15 catalysts can be recycled and reused up to six cycles without any loss in the catalytic performance.

Background: penta-1,4-diene-3-one oxime ether and quinazolin-4(3H)-one derivatives possess favorable agricultural activities. Aiming to discover novel molecules with highly-efficient agricultural activities, a series of penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold were synthesized and evaluated for their antiviral activities. Result: Antiviral bioassays indicated that some title compounds exhibited significant antiviral activity against tobacco mosaic virus (TMV). In particular, compounds 8c, 8j and 8k possessed appreciable curative activities against TMV in vivo, with half-maximal effective concentration (EC50) values of 138.5, 132.9 and 125.6 mu g/mL, respectively, which are better than that of ningnanmycin (207.3 mu g/mL). Furthermore, the microscale thermophoresis experiments (MST) on the interaction of compound 8k with TMV coat protein (TMV CP) showed 8k bound to TMV CP with a dissociation constant of 0.97 mmol/L. Docking studies provided further insights into the interaction of 8k with the Arg90 of TMV CP. Conclusions: Sixteen penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold were designed, synthesized, and their antiviral activities against TMV were evaluated. Antiviral bioassays indicated that some target compounds exhibited remarkable antiviral activities against TMV. Furthermore, through the MST and docking studies, we can speculate that 8k inhibited the virulence of TMV by binding Arg90 in TMV CP. These results indicated that this kind of penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold could be further studied as potential alternative templates in the search for novel antiviral agents.

A series of forty a-substituted chalcones were synthesized and screened for their antiproliferative activities against HCT116 (colorectal) and HCC1954 (breast) cancer cell lines. Compounds 5a and 5e were found to be the most potent compounds with GI(50) values of 0.63 mu M and 0.725 mu M in HCC1954 cell line and 0.69 mu M and 1.59 mu M in HCT116 cell line, respectively. Both compounds induced a G2/M cell cycle arrest and caused apoptotic cell death in HCT116 cells as shown by the induction of PARP cleavage. The compounds also stabilized p53 in a dose-dependent manner in HCT116 cells following 24-hour treatment. Furthermore, both 5a and 5e were able to overcome multidrug resistance in two MDR-1 overexpressing multidrug resistant cell lines.

Plinabulin, a synthetic analog of the marine natural product diketopiperazine phenylahistin, displayed depolymerization effects on microtubules and targeted the colchicine site, which has been moved into phase III clinical trials for the treatment of non-small cell lung cancer (NSCLC) and the prevention of chemotherapy-induced neutropenia (CIN). To develop more potent anti-microtubule and cytotoxic derivatives, the co-crystal complexes of plinabulin derivatives were summarized and analyzed. We performed further modifications of the tert-butyl moiety or C-ring of imidazole-type derivatives to build a library of molecules through the introduction of different groups for novel skeletons. Our structure-activity relationship study indicated that compounds 17o (IC50 = 14.0 nM, NCI-H460) and 17p (IC50 = 2.9 nM, NCI-H460) with furan groups exhibited potent cytotoxic activities at the nanomolar level against various human cancer cell lines. In particular, the 5-methyl or methoxymethyl substituent of furan group could replace the alkyl group of imidazole at the 5-position to maintain cytotoxic activity, contradicting previous reports that the tert-butyl moiety at the 5-position of imidazole was essential for the activity of such compounds. Immunofluorescence assay indicated that compounds 17o and 17p could efficiently inhibit microtubule polymerization. Overall, the novel furan-diketopiperazine-type derivatives could be considered as a potential scaffold for the development of anti-cancer drugs.

Immobilized piperazine on the surface of graphene oxide (piperazine-GO) is synthesized and characterized by different methods such as FT-IR, solid-state(29)Si{H-1} and(13)C{H-1} CP/MAS NMR, elemental analysis, TGA, TEM, FE-SEM, XPS, and TPD. Subsequently, it is used as a heterogeneous bifunctional acid-base catalyst for the efficient multicomponent reaction of malononitrile, different active compounds containing enolizable C-H bonds and various aryl/alkyl aldehydes in aqueous ethanol. A wide variety of 2-amino-3-cyano-4H-chromenes are synthesized in the presence of this heterogeneous catalyst in good to high yields and with short reaction times. The catalyst is easily separated and reused for at least six times without significant loss of activity. The acidic nature of GO improves the catalytic activity of the supported piperazine and also provides heterogeneity to the catalyst. Use of aqueous ethanol as a green solvent, high turnover numbers (TON), facile catalyst recovery and reuse, simple work-up and generality of the method make this protocol an environmentally benign procedure for the synthesis of the title heterocycles.

Generation and screening of oxime libraries by competitive MS Binding Assays represents a powerful tool for the identification of new compounds, with affinity to mGAT1, the most abundant plasma membrane bound GABA transporter in the CNS. By screening a guvacine derived oxime library, new potent inhibitors of mGAT1 had been revealed. In the present study, oxime libraries generated by reaction of a large excess of a rac-nipecotic acid derivative displaying a hydroxylamine functionality in which various aldehydes under suitable conditions, were examined for new potent inhibitors of mGAT1. The pK(i) values obtained of the best hits were compared with those of related compounds displaying a guvacine instead of a nipecotic acid subunit as hydrophilic moiety. Amongst the new compounds one of the most affine ligands of mGAT1 known so far (pK(i)= 8.55 +/- 0.04) was found.
