The synthesis of 5-acetyl-6-methyl-4-(1,3-diphenyl-1H-pyrazol-4-yl)-3,4-dihydropyrmidin-2(1H)-thione was achieved by one-pot three-component synthesis using CaCl2 in refluxing EtOH. The starting compound was utilized to synthesize a new series of 5-pyrazolyl; isoxazolyl; pyrimidinyl derivatives via the synthesized chalcone. Also, fused isoxazolo [5,4-d]pyrimidine and pyrazolo[3,4-d]pyrimidine were obtained by the treatment of 5-acetyl derivative with hydroxyl amine and/ or hydrazine hydrate. Also, the thiosemicarbazide derivative was prepared and utilized to synthesize other new thiazole derivatives. The structures of all compounds have been established on the basis of their analytical and spectral data. All compounds was also evaluated for their antibacterial and antifungal activity against various strains of bacteria and fungi. Also, the anti-inflammatory activity of some of synthesized compounds was evaluated using the carrageenan induced paw oedema test in rats using indomethacin as the reference drug.

One of the fundamental and highly valuable transformations in organic chemistry is the nucleophilic substitution of alcohols. Traditionally, these reactions require strategies that employ stoichiometric hazardous reagents and are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an S(N)2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C bonds. Furthermore, we also demonstrate that this method can be used for the preparation and late-stage functionalization of pharmaceuticals, as highlighted by the syntheses of thiocarlide, butoxycaine, and pramoxine.

A near-infrared fluorescent probe plays an important role in biosensing and bioimaging because of its high efficiency, sensitivity and negligible background interference in vivo. Azobenzene derivatives demonstrate well-known sensitivity to light and are unique enzyme-responsive candidates in drug delivery and biological detection because the azo double bond can be cleaved by azoreductase. Herein, a novel near-infrared probe of an amphiphilic block copolymer with biological compatibility was synthesized. The azobenzene group attached with the near-infrared fluorescent group AzaBODIPY (boron-dipyrromethenes) linked the hydrophilic (PEG) and hydrophobic (PLA) segments to form the amphiphilic block copolymer PEG-AzaBODIPY-AZO-PLA. PEG(398)-AzaBODIPY-AZO-PLA(144) self-assembled into drug-loaded spherical micelles. The self-assemblies were non-fluorescent owing to the aggregation-induced quenching (ACQ) effect. Triggered by azoreductase, the PEG and PLA segments were disconnected due to the cleavage of the azo bond. This caused the disassembly of the micelles and the subsequent release of the encapsulated drug. Upon disassembly, the emission of the near-infrared fluorescence was activated by the elimination of the ACQ effect. Furthermore, the fluorescence intensity of the self-assemblies in solution increased continuously with drug release. The fluorescence reporting drug release demonstrates the potential applications in biosensing and controlled drug release in the colon of the human intestine.

From a collection containing more than 1500 academic compounds, in silico screening identified a hit for the human A(1) adenosine receptor containing a new purine scaffold. To study the structure activity relationships of this new chemical series for adenosine receptors, a library of 24 purines was synthesized and tested in radioligand binding assays at human A(1), A(2A), A(2B) and A(3) adenosine receptor subtypes. Fourteen molecules showed potent antagonism at A(1), A(3) or dual A(1)/A(3) adenosine receptors. This purine scaffold is an important source for novel biochemical tools and/or therapeutic drugs.

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp(2))-H diphosphorylation. This reaction represents a rare example of realizing the challenging double C-P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

One-pot synthesis of hydrazinyl-4-phenyl-1,3-thiazole derivatives was developed by three-component reaction of various ketones or aldehydes, phenacyl chloride, and thiosemicarbazid in the presence of choline chloride/urea as a deep eutectic solvent (DES) at 70 degrees C. The products formed in excellent yields over short reaction times under an environmentally friendly condition. This method develops by using an environmentally benign synthetic method along with the use of a cost-effective catalyst. The study of antibacterial activity revealed that the compounds (4j, 4k, 4l, 4m, 4s, and 4t) showed good inhibition toward Escherichia coli.

Oxidative esterification of biomass-derived 5-(hydroxymethyl) furfural (HMF) and furfural and their derivatives has been performed using a simple MnO2/NaCN system. The developed method allows the selective one-pot transformation of HMF to dimethyl furan-2,5-dicarboxylate (FDME) in 83% isolated yield without the formation of a free acid. Simplification of FDME production provides the missing link for manufacturing sustainable value-added materials from biomass. Addition of water to the oxidative system allows fine-tuning of reaction selectivity to obtain the previously difficult-to-access pure methyl 5-(hydroxylmethyl)furan-2-carboxylate in one step directly from the unprotected HMF without chromatographic separation.

In search of potent anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 – 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E-2 (PGE(2)) suppression ability on IFN-gamma/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl)-1-(1H-pyrrol-2-yl) prop-2-en-1-one (compound 16) exhibiting remarkable inhibition activity towards PGE(2) and NO production with IC50 values of 0.5 +/- 1.5 mu M and 12.1 +/- 1.5 mu M, respectively. Physicochemical and ADMET studies showed that majority of the compounds obey to Lipinski’s rule of five (RO5) having high blood brain barrier (BBB) penetration, human intestinal absorption (HIA), P- glycoprotein (PgP) inhibition and plasma binding protein (PPB) inhibition. The obtained atomic coordinates for the single-crystal XRD of 16 were then applied in a molecular docking simulation, and compound 16 was found to participate in a number of important binding interactions in the binding sites of ERK and mPGES-1. Based on these results, we have observed the potential of compound 16 as a new hit anti-inflammatory agent, and these findings could serve as a basis for further studies on its mechanism of action.

A series of triphenyl substituted pyrimidines as analogous of colchicine and combretastatin A-4 was synthesized and evaluated for the antiproliferative potential. The compounds were screened against MDA-MB-231, HCT-116 and HT-29 cell lines using MTT assay. Most of the compounds displayed antiproliferative activity in low to sub micro molar concentration. Amongst the synthesized derivatives, compounds HK-2, HK-10 and HK-13 were found to be effective against all the three cancer cell lines. HK-2 exhibited IC50 values of 3.39 mu M, 4.78 mu M and 4.23 mu M, HK-10 showed IC50 values of 0.81 mu M, 5.89 mu M, 4.96 mu M and HK-13 showed IC50 values 3.24 mu M, 4.93 mu M and 4.73 mu M against MDA-MB-231, HCT-116 and HT-29 cancer cell lines, respectively. HK-10 was found to be the most potent compound in the series with IC50 values of 0.81 mu M against MDA-MB-231. In the cell cycle analysis, HK-2 and HK-10 showed cell arrest at G2/M phase of the cell cycle while HK-13 inhibited cell growth at the G1/G0 phase. All the three compounds showed cell death induced through apoptosis. In the docking studies, HK-2, HK-10 and HK-13 were found to fit well in the colchicine binding site of the tubulin. Some of the compounds in the current series were found to be promising against all the three cancer cell lines and may act as potent leads for further development.
