In pursuit of neuroprotective and antimicrobial agents, a series of 1,2,4-triazolo[3,4-b]1,3,4-thiadiazole incorporated thieno[2,3-d]pyrimidine derivatives 10 a-l has been designed, synthesized. The final target compounds were screened for neuroprotective, neurotoxic and antibacterial activities. The compounds derived from 4-methylphenyl (10 a) and 4-nitrophenyl (10 c) have showed good neuroprotective activity against H2O2 induced PC12 cell death at respective EC50 values of 10.44, 14.12 mu g/mL. However 10 b and 10 k showed superior neurotoxic effects than rest of the compounds with respective CC50 values of 100.16, 120 mu g/mL. Potent antibacterial activity was shown by 10 f (R=-Me, R-2=-OMe), 10 h (R=-Me, R-2=-Cl) against the four bacterial pathogens such as S.aureus, B.subtilis, E.coli and P.aeruginosa at low minimum inhibitory concentration (MIC) range. Further, in silico docking studies were performed for all the synthesized compounds with C(30) carotenoid dehydrosqualene synthase, Gyrase A and LpxC bacterial proteins. Interestingly, 10 f, 10 h showed good binding affinities with target proteins and these results are in good compliance with the in vitro activity profile data.

A copper-catalyzed procedure enabling dynamic carbon isotope exchange is described. Utilizing the universal precursor [C-14]CO2, this protocol allows to insert, in one single step, the desired carbon tag into carboxylic acids with no need of structural modifications. Reducing synthetic costs and limiting the generation of radioactive waste, this procedure will facilitate the access to carboxylic acids containing drugs and accelerate early C-14-based ADME studies supporting drug development.

Protein arginine methyltransferases 5 (PRMT5) represents an attractive drug target in epigenetic field for the treatment of leukemia and lymphoma. Here, a series of N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)amide derivatives targeting PRMT5 were designed with structure-based approach and synthesized. Among them, compound 46 showed potent and selective PRMT5 inhibition activity with an IC50 of 8.5 nM, which was approximately equivalent with the phase 1 clinical trial PRMT5 inhibitor GSK-3326595 (IC50 = 5.5 nM). Compound 46 also displayed pronounced anti-proliferative activity in MV4-11 cells (GI(50) =18 nM) and antitumor activity in MV4-11 mouse xenografts model.

A novel series of 2-(3-methyl-1,6-diphenyl-1H-pyrazolo[3,4-b]pyridin4-yl)-5-aryl-1,3,4-oxadiazoles (4a-4h) has been synthesized from corresponding hydrazones (3a-3h) and evaluated their antiplatelet aggregation effect induced by arachidonic acid and collagen. Spectral data and elemental evaluation were used to confirm the structure of the compounds while molecular docking against cyclooxygenase 1 and 2 (COX1 & COX2) and quantitative structure-activity relationship (QSAR) were performed in describing their antiplatelet potential. All synthesized compound exhibited more than 50% platelet aggregation inhibition against both arachidonic acid and collagen. Antiplatelet activities results showed that 4b and 4f compounds have highest % inhibition against arachidonic acid. High Egap and ionization potential values showed that the compound 4d, 4e and 4f were supposed to be more active and good electron donor while 4b, 4c, 4d, 4e, 4g and 4h might be more active due to more electrophilic sites. Interaction with more than one residues in the binding pocket of COX-1 in comparison with aspirin and ligand efficacy (LE) consequences showed that compounds have excellent action potential for COX-1. Computational evaluations are in good agreement with antiplatelet activities of the compounds. All compounds might be promising antiplatelet agents especially 4b, 4f and helpful in the synthesis of new drugs for the treatment of cardiovascular diseases (CVDs).

Piperine is a component of pepper which has earlier been reported as anticancer active compound. This work is emphasized on the design and synthesis of new hybrid piperine analogs by coupling piperine with the amine group of oxadiazoles and thiadiazoles. The new series of twelve piperine analogs was been tested for in vitro anti-proliferative activity using sulforhodamine B (SRB) assay test against MCF-7, PC-3, and HeLa cell lines. Among the twelve synthesised molecules piperine derivative with oxadiazole baring hydroxyl group (3) exhibits the higher activity against MCF-7 cell line than the reference drug Adriamycin and also displays the highest binding energy in the in silico studies. The other analogs are moderately active.

A metal-free cross coupling between common CH2Cl2 and carboxylic acids has been achieved with K2CO3 as the sole additive. This simple protocol is a convenient and cost-effective route to synthesize methylene diesters from a wide scope of carboxylic acids substrates with good functional group tolerance. Several gram-scale reactions have been performed to evaluate the effectiveness and practicality of this protocol.

Herein we describe the development of an efficient one-pot regioselective synthesis protocol to obtain N-protected or N-deprotected 1,5-diaryl-3-amino-1,2,4-triazoles from N-acyl-N-Boc-carbamidothioates. This improved protocol using microwave irradiation and low reaction times (up to 1 h) furnished desired compounds in yields ranging from 50 to 84%. This chemistry is useful for a variety of aromatic groups with electronically diverse substituents. The design and correct derivation of the amino group led to compounds able to inhibit cholinesterases with good IC50 of up to 1 mu M. Also, the mode of action (mixed-type) and SAR analysis for this series of compounds was described by means of kinetic and molecular modelling evaluations, showing potential for this class of compounds as new scaffolds for this biological activity.

The TEMPO-catalyzed oxidation of alcohols to aldehydes has emerged to one of the most widely applied methodologies for such transformations. Advantages are the utilization of sodium hypochlorite, a component of household bleach, as an oxidation agent and the use of water as a co-solvent. However, a major drawback of this method is the often occurring strict limitation to use dichloromethane as an organic solvent in a biphasic reaction medium with water. Previous studies show that dichloromethane cannot easily be substituted because a decrease of selectivity or inhibition of the reaction is observed by using alternative organic solvents. Thus, up to now, only a few examples are known in which after a tedious optimization of the reaction dichloromethane could be replaced. In order to overcome the current limitations, we were interested in finding a TEMPO-oxidation method in alternative organic solvents, which is applicable for various alcohol oxidations. As a result, we found a method for N-oxyl radical-catalyzed oxidation using sodium hypochlorite as an oxidation agent in nitriles as an organic solvent component instead of dichloromethane. Besides the oxidation of aromatic primary alcohols also aliphatic primary alcohols, secondary alcohols as well as dialcohols were successfully converted when using this method, showing high selectivity towards the carbonyl compound and low amounts of the acid side-product.

Carbon-hydrogen (C-H) bond functionalization streamlines synthesis by increasing step- and atom-economies. This approach, catalyzed by Rh(III), is combined with the alpha-arylation of ketone-derived silyl enol ethers to achieve a direct cross-coupling event. The advancement of electron-rich alkenes as substrates is enabled through the use of a silver additive and complements existing C-H activation methods that transform enol ester derivatives and electron-deficient alkenes. A Rh(III)/(V)/(III) catalytic cycle is proposed to rationalize mechanistic observations.
