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.

Four new 4′-dimethoxyphenyl-(2,6-di-2-pyrazinyl) pyridines (1-4) were synthesised by a facile one-pot method using 2-acetylpyrazine and n,n’-dimethoxybanzaldehydes. All compounds (1-4) were characterised by H-1 and C-13{H-1} NMR, and FT-IR spectroscopy. The molecular structure of compounds 1, 2, and 3 was also confirmed by single crystal X-ray diffraction. There exists CH center dot center dot center dot N, CH center dot center dot center dot O and C center dot center dot center dot C aromatic stacking type of intermolecular secondary interactions which resulted into supramolecular structures in compounds 1-3. The Hirshfeld surface analysis was carried out for the confirmation of intermolecular secondary interactions. The dihedral angles between substituted dimethoxyphenyl ring (B) and central pyridine (A) and pyrazine rings (C and D) are in the range of 33-45 degrees. The photophysical properties were studied by UV-Visible and fluorescence spectroscopy and electrochemical properties by cyclic voltammetry. In the UV-Visible spectra, the compounds, 1-4 showed two strong bands at lambda(max), 236-238 and 284-293 nm attributed to the intramolecular charge transfer (pi-pi*) transitions. When these compounds were excited at 350 nm observed emission bands at lambda(em), 463, 511, 462, and 407 nm respectively. The compounds, 1-3 were showed an oxidation peak, (E-OX, 1.18, 1.57 and 1.25 V) but compound 4 showed two oxidation peaks (E-OX, 1.20 and 1.84 V). Astonishingly, only compound, 3 have shown a reduction peak at (E-red, 1.33 V) but there was no reduction peak in 1, 2 and 4. This shows that the compound, 3 undergo reversible redox reaction.

Background: Chalcones substituted by methoxyl groups have presented a broad spectrum of bioactivities, including antifungal, antibacterial and antiproliferative effects. However, a clear and unambiguous investigation about the relevance of this substituent on the chalcone framework has not been described. Objective: The purpose of this work is to assess the antibacterial, antifungal and antiproliferative activities of the two series of seventeen synthesized regioisomeric methoxychalcones. Series I and II were constituted by cbalcones substituted by methoxyl groups on rings A (5-12) and B (13-21), respectively. In addition, the library of methoxychalcones was submitted to in silico drug-likeness and pharmacokinetics properties predictions. Methods: Methoxychalcones were synthesized and their structures were confirmed by NMR spectral data analyses. Evaluations of antimicrobial activity were performed against five species of Candida, two Gram-negative and five Gram-positive species. For antiproliferative activity, methoxychalcones were evaluated against four human tumorigenic cell lines, as well as human non-tumorigenic keratinocytes. Drug-likeness and pharmacokinetics properties were predicted using Molinspiration and PreADMET toolkits. Results: In general, chalcones of series I are the most potent antifungal, antibacterial and antiproliferative agents. 3′, 4′, 5′-Trimethoxychalcone (12) demonstrated potent antifungal activity against Candida krusei (MIC = 3.9 mu g/mL), eight times more potent than fluconazole (reference antifungal drug). 3′-Methoxychalcone (6) displayed anti-Pseudomonas activity (MIC = 7.8 mu g/mL). 2′,5′-Dimethoxychalcone (9) displayed potent antiproliferative effect against C-33A (cervix), A-431 (skin) and MCF-7 (breast), with IC50 values ranging from 7.7 to 9.2 mu M. Its potency was superior to curcumin (reference antiproliferative compound), which exhibited IC50 values ranging from 10.4 to 19.0 mu M. Conclusion: Our studies corroborated the relevance of methoxychalcones as antifungal, antibacterial and antiproliferative agents. In addition, we elucidated influence of the position and number of methoxyl groups toward bioactivity. In silico predictions indicated good drug-likeness and pharmacokinetics properties to the library of methoxychalcones.

Solid-state acid-responsive materials are promising for the tunability of their intrinsic properties. However, the relationship between molecular structure and emission shift as a response to acid stimuli has not been systematically studied. Herein, we report the effect of protonation and subsequent intramolecular hydrogen bonding on the photophysical properties of compounds (MPP-s, MPP-d, and MPP-d-CN) with different conjugation modes between the electron-donating dimethoxyl phenyl and the electron-withdrawing benzothiazole ring. The results established that the stronger the intramolecular charge transfer feature of the compound, the smaller is the emission shift after acid stimuli. Our studies also indicated that the conjugation mode significantly affected the solid-state packing mode: MPP-s and MPP-d tended to form dimers, while MPP-d-CN exhibited the strongest aggregation-induced emission enhancement (AIEE). The exploration of structure-property relationship would provide experimental and theoretical guidance in designing acid-responsive molecular switches and developing high-performance AIEE-active luminogens.

Diene-transmissive Diels-Alder (DTDA) sequences are extraordinarily powerful processes for the generation of fused bicyclic systems. Nonetheless, only stable dienophiles have previously been deployed. Herein we report DTDA sequences with a variety of substituted [3]dendralenes in the first study to deploy arynes as dienophiles. We demonstrate the one-flask generation of complex, aromatic-ring-containing, multicyclic systems of relevance to medicinal chemistry. These synthetic operations provide numerous successful examples of the otherwise challenging and rarely reported intermolecular Diels-Alder reaction of acyclic 1,3-butadienes with arynes, which is made possible due to the exalted reactivity of dendralenic dienes.

In order to explore and develop new anticancer agents, three series of 2-phenylbenzimidazoles, 15-46, were condensed under simple and mild conditions using sodium metabisulfite as an oxidation agent and another series, 47-55, were obtained via a reduction reaction using sodium borohydride. All the compounds synthesized were evaluated for their in vitro anticancer activities against three human cancer cell lines. The novel compound 38 was found to be the most potent multi cancer inhibitor against A549, MDA-MB-231, and PC3 cell lines (IC50 values 4.47, 4.68 and 5.50 mu g mL(-1), respectively). In addition, compound 40 exhibited the best IC50 value of 3.55 mu g mL(-1) against the MDA-MB-231 cell line. The results demonstrated that introducing a new substituent to compounds 37-55 could improve their antiproliferative activities.

Imidazoline-based small molecule inhibitors of p53-MDM2 interaction intended for the treatment of p53 wild-type tumors are the promising structures for design of anticancer drugs. Based on fragment approach we have investigated a key role of substituents in cis-imidazoline core for biological activity of nutlin family compounds. Although the necessity of the substituents in the phenyl rings of cis-imidazoline has been shown, there are no studies in which the replacements of a halogen by other substituents have been investigated. A series of simple cis-imidazoline derivatives containing halogen, hydroxy and alkoxy-substituents were synthesized. The biological activity of the compounds was studied using assays of cytotoxicity (MTT) and p53 level. It was found that the hydroxyl-derivatives were not cytotoxic whereas the alkoxy analogues were the same or more active as halogen-substituted compounds in cell viability test. The synthesized alkoxy derivatives induced an increase of p53 level and did not promote necrotic cell death in the concentration up to 40 mu M.

A solid acid catalyst bearing sulphamic acid on sawdust (SA@Sawdust) was designed as a novel heterogeneous catalyst. The structure of prepared catalyst was assessed by various spectroscopic techniques such as FT-IR, field emission scanning electron microscopy and energy dispersive X-ray, thermogravimetric analysis, solid-state CP/MAS C-13-NMR spectroscopy, and CHNS analysis. The efficiency of prepared catalyst was explored for synthesis of diverse 1,8-dioxo-octahydroxanthene derivatives. The mild reaction conditions are found to be more compatible with a wide range of functional groups. The obtained products could be conveniently separated from the reaction mixture by simple filtration, and the catalyst is recovered and reused for next cycle without significant loss in catalytic efficiency. The alluring features of this synthetic route are operational simplicity, shorter reaction time, high conversion, wide substrate scope, easy work-up procedure, and reusability of catalyst.
