A new series of 2,4-disubstituted-2-thiopyrimidines 6a-t, 9a, and 9b was efficiently designed and synthesized as antiangiogenic and cytotoxic agents. Compounds 6j, 6l, and 6d showed IC50 values of 1.23, 3.78, and 3.84 mu M, respectively, against the vascular endothelial growth factor receptor-2 (VEGFR-2). Most of the synthesized 2-thiouracils showed antiproliferative activity against the HepG2 cell line (hepatocellular carcinoma) in the micromolar range, for instance, 9b, 6l, 6m, 6n, and 6j displayed IC50 = 7.92, 8.35, 8.51, 9.59, and 13.06 mu M, respectively, relative to sorafenib (III; IC50 = 10.99 mu M). Also, compounds 6j, 9a, 6m, and 6s (IC50 = 15.21, 16.96, 17.68, and 18.15 mu M, respectively) are the most potent compounds against the UO-31 cell line. Further evaluation of the effect of the synthesized candidates on VEGFR-2 in the HepG2 cell line demonstrated that compounds 6j and 6l exhibit VEGFR-2 inhibitory activity of 87% and 84%, respectively, relative to sorafenib (III; 92%). In silico docking of the synthesized hits into the binding site of VEGFR-2 showed their ability to perform the main binding interactions with the key amino acids in the binding site. Studying the in silico predicted ADME (absorption, distribution, metabolism, and excretion) parameters for the synthesized thiouracils demonstrated that they have favorable pharmacokinetic and drug-likeness properties. These results demonstrate that the 2,4-disubstituted thiouracils 6 and 9 have not only favorable antiangiogenic and antiproliferative activity but also satisfy the criteria required for the development of orally bioavailable drugs. Consequently, they represent a biologically active scaffold that should be further optimized for future discovery of potential hits.

Stable phenoxyl radicals H-bonded to phenols were successfully isolated. The effect of the intermolecular Hbonding to the concerted proton coupled electron transfer (CPET) reactions of the aldimines and the stability and spin distribution of the H-bonded phenoxyls are reported. Salts of iminium-phenol derivatives as cations and the corresponding imine-phenolato derivatives coordinated to zinc(II) as anions, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+), were isolated, where ArOH are aldimine derivatives. Notably, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts undergo CPET reactions in air affording phenoxyl analogues, [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN. [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts incorporate intermolecular iminium-phenolato, [(Zn)Ar-O–+HN=CH-] H-bonds, while [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN moieties contain intermolecular phenoxyl-phenol, [Ar-O-HO-Ar](center dot), H-bonds. The phenoxyls are presented in two forms, [(Zn)Ar-O-center dot—HO-Ar (zinc phenoxyl) <-> (Zn)Ar-OH—O-center dot-Ar (free phenoxyl)]. In crystals, the spin density scatters on both phenolic fragments corresponding to a delocalized state, while in solution the latter form has been calculated as a ground electronic state. The X-band EPR spectra of crystals, solutions and frozen glasses were analyzed. The powder spectra at g = 2.0030 +/- 0.0005 and the frozen glass spectra at g = 2.0075 +/- 0.0003 follow the hyperfine patterns due to N-14 (I = 1) nuclei. In fluid solutions, the g values of the hyperfine signals due to (14) N and H-1 nuclei are 2.0078 +/- 0.0001. 1-3 exhibit absorption bands at 350-390 nm due to pi ->pi* intraligand charge transfer (ILCT) transitions, while the radical species, in addition to pi ->pi transitions at 405-440 nm, display phenol to phenoxyl intervalence charge transfer (WCT) transitions at 600-650 nm. The cyclic voltammograms (CVs) of 1-3 depend on the scan rates; at lower scan rates (100-400 mV/s) the CPET reactions occur at -0.92 to -0.96 V versus Fc(+)/Fc couple, whereas at higher scan rates (1000-2400 mV/s), the oxidation occurs by the electron transfer (ET) path at 0.05-0.12 V. Thus, a potential shift of similar to 1.0 V is recorded due to CPET reactions facilitated by H-bonding.

Three different loadings of MnO2 on hydroxyapatite (MnO2/Hap) were synthesized and the hydroxyapatite supported MnO2 materials were characterized by several analytical techniques including FT-IR, P-XRD, TEM and SEM analysis. 3% MnO(2/)HAp material proved highly efficient catalyst for the synthesis of a series of ten pyran-carboxamide derivatives (yield 91-98%) in aqueous medium at room temperature (RT) conditions, via one-pot multi-component reaction, of which nine were new moieties.

Solvent-free, atom-efficient, and mechanochemically activated reactions have emerged as synthetic strategy for sustainable chemistry. Herein we report a new mechanochemical approach for the amide coupling of carboxylic acids and amines, mediated by combination of (1-cyano-2-ethoxy-2-oxoethylidenaminooxy)-dimethylaminomorpholinocarbenium hexafluorophosphate (COMU) or N,N,N’,N’-tetramethylchloroformamidinium hexa-fluorophosphate (TCFH) and K2HPO4. The method delivers a range of amides in high yields (70-96%) and fast reaction rates. The reaction protocol is mild, keeps stereochemical integrity of the adjacent to carbonyl stereocenters, and streamlines isolation procedure for solid amide products. Minimal waste is generated due to the absence of bulk solvent. We show that K2HPO4 plays a dual role, acting as a base and a precursor of reactive acyl phosphate species. Amide bonds from hindered carboxylic acids and low-nucleophilic amines can be assembled within 90 minutes by using TCFH in combination with K2HPO4 or N-methylimidazole. The developed mechanochemical liquid-assisted amidation protocols were successfully applied to the challenging couplings of all six carboxylate functions of biotin[6]uril macrocycle with phenylalanine methyl ester, resulting in 80% yield of highly pure hexa-amide-biotin[6]uril. In addition, fast and high-yielding synthesis of peptides and versatile amide compounds can be performed in a safe and environmentally benign manner, as verified by green metrics.

An expedient and eco-friendly synthesis of 1-aryl/heteroaryl-[1,2,4]-triazolo[4,3-a]quinoxalin-4(5H)-ones (4) has been accomplished via iodobenzene diacetate mediated oxidative intramolecular cyclization of 3-(2-(aryl/heteroarylidene)hydrazinyl)-quinoxalin-2(1H)-ones (3). Ten synthesized compounds 3 and 4 (10-40 mu g) on irradiation with UV light at lambda(max) 312 nm could lead to cleavage of supercoiled pMaxGFP DNA (Form I) into the relaxed DNA (Form II) without any additive. Further, DNA cleaving ability of triazoles was quantitatively evaluated and was found to be dependent on its structure, concentration, and strictly on photoirradiation time. Mechanistic investigations using several additives as potential inhibitors/activator revealed that the DNA photocleavage reaction involves Type-I pathway leading to formation of superoxide anion radicals (O-2(-center dot)) as the major reactive oxygen species responsible for photocleavage process.

A series of substituted benzoate-bridged dichromium(II, II) complexes [Cr-2(RCO2)(4)(THF)(2)] ([Cr-2]), where RCO2- is substituted benzoate, was synthesized and its structural and magnetic properties were investigated. The orbital energies, as well as magnetic coupling energies, were also investigated using computational approaches. The HOMO/LUMO energy levels of the complexes are strongly dependent on the acidity, i.e., pK(a), of the corresponding benzoic acids (RCO2H), revealing a linear trend in the respective groups of non-ortho, mono-ortho, and bi-ortho substituted groups. The Cr center dot center dot center dot Cr magnetic coupling constant (E-S (T)) is little affected by pK(a); instead, the E-S (T) is associated with the HOMO/LUMO gap and strongly correlated with the Cr center dot center dot center dot Cr distance.

A simple and efficient eco-friendly method was developed for the synthesis of new benzo[4,5]imidazo[1,2-a]pyrimidine-3-carbonitrile derivatives in excellent yields. The synthesis was achieved through the reaction of 2-aminobenzimidazole, aldehydes and active nitriles (malononitrle or ethyl cyanoacetae) in the presence of silica sulfuric acid/ethylene glycol. This protocol offers very short reaction times (in some cases, reaction times were reduced to five minutes), high yields and low cost. This method thus provides an improvement over the existing methods.
