Diarylimidazo[2,1-b]-1,3,4-thiadiazoles I (R = Cl, R1 = H, Br, Me, Ph, Cl; R = Me, R1 = Cl, Ph) are prepared by the reaction of α-haloketones with 2-aminothiadiazoles II, or more conveniently, by treating II directly with ketones in the presence of NBS. Bromination of I (R = R1 = Cl) furnishes a 5-bromo-2,6-diarylimidazo[2,1-b]thiadiazole derivative The antimicrobial activity of I (R = R1 = Cl) and a derivative has been evaluated; they were found to be inactive.

HDAC and CDK inhibitors have been demonstrated to be synergistically in suppressing cancer cell proliferation and inducing apoptosis. In this work, we incorporated the pharmacophore groups of HDACs and CDKs inhibitors into one mol. to design and synthesize a series of purin derivatives as HDAC/CDK dual inhibitors. The lead compound I, showing good HDAC1 and CDK2 inhibitory activity with IC50 values of 5.8 and 56 nM, resp., exhibited attractive potency against several cancer cell lines in vitro. This work may lead to the discovery of a novel scaffold and potential dual HDAC/CDK inhibitors.

Sahoo, Manoj Kumar; Pradhan, Sourav; Kim, Dongwook; Park, Jung-Woo; Chang, Sukbok published the artcile< Head-to-Head Homocoupling of Ynamides via a Dual Activation Mode of Triple Bonds by Half-Sandwich Metal Complexes>, SDS of cas: 67421-02-7, the main research area is rhodium mediated cyclometalation homocoupling terminal ynamide amidosulfonyl compound; dienyl amidosulfonyl rhodacyclic complex preparation electrochem optimized geometry DFT; crystal structure dienyl amidosulfonyl rhodacyclic iridacyclic complex; mol structure dienyl amidosulfonyl rhodacyclic iridacyclic complex.

Reported herein is the half-sandwich Rh-mediated head-to-head homocoupling of terminal ynamides to furnish dienyl bisamido rhodacyclic complexes, where the Rh-vinyl bond was formed selectively at the α-C to the N atom. This transformation was extended to include piano-stool Ru and Ir complexes to display an analogous homocoupling reactivity. Based on d. functional theory studies, the reaction probably proceeds via a dual activation mode of the ynamide triple bonds: (i) generation of a zwitterionic keteniminyl metal species to induce an intramol. chloride transfer and (ii) syn-carbometalation of the 2nd coordinated alkynes by the alkenyl metal intermediate. An oxidative transformation of the homocoupled metal complexes gave multifunctional dienyl bisamide compounds

El Abbouchi, Abdelmoula; El Brahmi, Nabil; Hiebel, Marie-Aude; Bignon, Jerome; Guillaumet, Gerald; Suzenet, Franck; El Kazzouli, Said published the artcile< Synthesis and biological evaluation of ethacrynic acid derivatives bearing sulfonamides as potent anti-cancer agents>, Application In Synthesis of 22952-32-5, the main research area is ethacrynic acid sulfonamide preparation anticancer human safety; Anti-cancer; Anti-proliferative; Cancer cells; Ethacrynic acid; Safety ratios; Sulfonamides.

A series of ethacrynic acid (2-[2,3-dichloro-4-(2-methylidenebutanoyl)phenoxy]acetic acid) (EA, Edecrin) containing sulfonamides linked via three types of linkers namely 1,2-ethylenediamine, piperazine and 4-aminopiperidine was synthesized and subsequently evaluated in vitro against HL60 and HCT116 cancer cell lines. All the EA analogs, excluding two derivs, showed anti-proliferative activity with IC50s in the micromolar range (less than 4 uM). Three derivatives I-III were selected for their interesting dual activity on HL60 cell line in order to be further evaluated against a panel of cancer cell lines (HCT116, A549, MCF7, PC3, U87-MG and SKOV3) as well as on MRC5 as a normal cell line. These compounds displayed IC50 values in nanomolar range against A549, MCF7, PC3 and HCT116 cell lines, deducing the discovery that piperazine or 4-aminopiperidine is the linker’s best choice to develop EA analogs with highly potent anti-proliferative activities own up to 24 nM. Besides, in terms of selectivity, those linkers are more suitable offering safety ratios of up to 63.8.

Cernicharo, J.; Cabezas, C.; Agundez, M.; Tercero, B.; Pardo, J. R.; Marcelino, N.; Gallego, J. D.; Tercero, F.; Lopez-Perez, J. A.; de Vicente, P. published the artcile< TMC-1, the starless core sulfur factory: discovery of NCS, HCCS, H2CCS, H2CCCS, and C4S and detection of C5S>, Category: chlorides-buliding-blocks, the main research area is chlorosuccinimide thioketene sulfur Taurus Mol cloud; Astrochemistry; ISM: individual (TMC-1); ISM: molecules; line: identification; molecular data.

We report the detection of the sulfur-bearing species NCS, HCCS, H2CCS, H2CCCS, and C4S for the first time in space. These mols. were found towards TMC-1 through the observation of several lines for each species. We also report the detection of C5S for the first time in a cold cloud through the observation of five lines in the 31-50 GHz range. The derived column densities are N(NCS) = (7.8 ± 0.6) x 1011 cm-2, N(HCCS) = (6.8 ± 0.6) x 1011 cm-2, N(H2CCS) = (7.8 ± 0.8) x 1011 cm-2, N(H2CCCS) = (3.7 ± 0.4) x 1011 cm-2, N(C4S) = (3.8 ± 0.4) x 1010 cm-2, and N(C5S) = (5.0 ± 1.0) x 1010 cm-2. The observed abundance ratio between C3S and C4S is 340, that is to say a factor of approx. one hundred larger than the corresponding value for CCS and C3S. The observational results are compared with a state-of-the-art chem. model, which is only partially successful in reproducing the observed abundances. These detections underline the need to improve chem. networks dealing with S-bearing species.
