Four-component, one-pot synthesis of (E)-N-benzylidene-3-(benzylthio)-5-(3,5-dimethyl-1H-pyrazol-1-yl)-4H-1,2,4-triazol-4-amines and their DNA binding and molecular docking studies

An efficient four-component strategy has been developed for the synthesis of a novel series of (E)-N-benzylidene-3-(benzylthio)-5-(3,5-dimethyl-1H-pyrazol-1-yl)-4H-1,2,4-triazol-4-amines in good yields.

NMR-Detected Host-Guest Proton Exchange as a Tool to Explore Surface/Volume Ratios and Fluid Filling of Internal and External Spaces of Porous Solids Containing Surface OH Groups

A solid-state H-1 magic-angle spinning (MAS) NMR method is described to characterize the internal pore spaces and the external void spaces of powdered mesoporous solids containing surface OH groups. This method is based on fast proton exchange between homogeneously distributed surface OH groups of the porous hosts and added guests containing exchangeable NH protons. The position of the coalesced NH/OH signal in a given local space depends on its surface/volume ratio (S/V). In the case of slow guest exchange between spaces with different S/V ratios, coalesced signals are observed for each space where the relative signal intensities reflect the mole fractions of the guests in the different spaces. This method was tested by performing H-1 MAS NMR experiments on the samples of liquid 4-methyl-1H-pyrazole (MPz) embedded in mesoporous silica of the MCM-41 type (2.9 nm pore diameter) and the SBA-15 type (8.9 nm pore diameter). To guarantee fast NH/OH proton exchange, the experiments were performed at 398 K well below the boiling point. Three distinct signals were observed for MPz assigned to (i) the internal cylindrical pores, (ii) the external interstitial void space between the packed particles, and (iii) the space outside the powdered solid containing neat liquid MPz. From the NMR data analysis, surface/ volume ratios are derived for the internal pores, which agree well with those obtained with a simple geometrical model after applying a surface-roughness correction. In addition, S/V ratios for the external space, as well as internal surface/external surface (S/S) and internal volume/external volume (V/V) ratios, are derived. It is shown that at low filling fractions, MPz preferentially enters the internal pores, but at larger fractions, MPz enters the external spaces. Moreover, it is shown that the final internal pore NH/OH ratio is achieved before the pores are filled. A scenario that rationalizes these findings in connection with the hydrogen-bonded states of MPz is presented where the number and the hydrogen-bonded state of guest molecules in a given pore are discussed.

p-TSA center dot H2O mediated one-pot, multi-component synthesis of isatin derived imidazoles as dual-purpose drugs against inflammation and cancer

A novel one-pot multicomponent reaction was performed to synthesize different imidazole and benzotriazole (BTA) isatin-based medicinally important compounds using (p-TSA center dot H2O) as an economical and operative acid catalyst. The yield of the products was found to be up to a maximum of 92% when using this catalyst. Antioxidant, anti-breast cancer and anti-inflammatory activities of these 13 isatin-based derivatives (named as 5a-m) were assessed. The inhibitory effects of these compounds were tested in vitro against cyclooxygenase-2 (COX-2, an enzyme responsible for inflammation) and phosphoinositide-3 kinase (PI3K, a key enzyme in breast cancer). Among the 13 isatin-based Imidazole derivatives, five compounds (5a, 5d, 5f, 5 k and 5l) were found to exhibit anti-inflammatory as well as anti-cancer activity, which was validated using HRBC stabilization assay (to show anti-inflammatory activity) and cytotoxicity in MCF-7 (breast cancer cell line) to provide proof for anticancer property of the compounds. The molecular interactions between the two enzymes were probed using molecular docking. Structure-Activity Relationship (SAR) and ADMET prediction results were also useful to screen the most effective imidazole derivatives and to establish them as putative COX-2 inhibitors/anti-inflammatory drugs. These selected compounds which showed appreciable activity against COX-2 and PI3K are promising drug candidates for the treatment of breast cancer and inflammation which is often associated with breast cancer pathophysiology.

Monocarboxylate transporter 1 and 4 inhibitors as potential therapeutics for treating solid tumours: A review with structure-activity relationship insights

Development of multidrug resistance (MDR) is one of the major causes leading to failure of cancer chemotherapy and radiotherapy. Monocarboxylate transporters (MCTs) MCT1 and MCT4, which are overexpressed in solid tumours, play a very important role in cancer cell survival and proliferation. These lactate transporters work complimentarily to drive lactate shuttle in tumour cells, which results in maintenance of H+ ion (pH) balance necessary for their survival. Inhibition of these transmembrane proteins has been demonstrated as a novel strategy to treat drug resistant solid cancers. Presently, only a few small molecule MCT1 inhibitors such as AZD3965 and AR-C155858 are known with clinical potential. Even lesser mention of MCT4 inhibitors, which include molecules having scaffolds such as pyrazole and indazole, is available in the literature. Current overview presents the status of recent developments undertaken in identification of efficacious MCT1 and/or MCT4 inhibitors as a potential anticancer therapy overcoming MDR. Further, detailed structure-activity relationships for different classes of compounds has been proposed to streamline the understandings learnt from ongoing research work. Through this review, we aim to highlight the importance of these excellent targets and facilitate future development of selective, potent and safe MCT1 and/or MCT4 inhibitors as promising chemotherapy for drug resistant cancer.

Sulfonic acid-functionalized Fe3O4-supported magnetized graphene oxide quantum dots: A novel organic-inorganic nanocomposite as an efficient and recyclable nanocatalyst for the synthesis of dihydropyrano[2,3-c]pyrazole and 4H-chromene derivatives

In this research, the main emphasis has been focused on the preparation of a novel Fe3O4-supported propane-1-sulfonic acid-grafted graphene oxide quantum dots (Fe3O4@GOQD-O-(propane-1-sulfonic acid)) that it was readily synthesized via a five-step procedure as a hitherto unreported magnetic nanocatalyst. This newly prepared Fe3O4@GOQD-O-(propane-1-sulfonic acid) nanocomposite was structurally well-established by different analytical techniques including Fourier transform infrared (FT-IR), X-ray diffraction (XRD), energy-dispersive X-ray (EDX), thermal gravimetric analysis (TGA), field emission gun-scanning electron microscope (FESEM), high-resolution transmission electron microscopy (HRTEM) and vibrating sample magnetometer (VSM) analyses. The high catalytic performance of this nanocomposite was exhibited in one-pot synthesis of dihydropyrano[2,3-c]pyrazole and 4H-chromene derivatives under mild conditions. Low reaction times, excellent yields of the products, benignity of the catalyst, easy reaction work-up and magnetic recyclability of the catalyst are the main advantages of the present protocol. Also, our research indicated that the Fe3O4@GOQD-O-(propane-1-sulfonic acid) could be reused up to five times without considerable loss of catalytic activity.

Enamines and Dimethylamino Imines as Building Blocks in Heterocyclic Synthesis: Reactions of DMF-DMA Reagent with Different Functional Groups

N,N-Dimethylformamide dimethyl acetal (DMF-DMA) reagent can react with different functional groups of organic compounds. Enamines and dimethylamino imines are obtained, when the DMF-DMA reagent is reacted with methylene, methyl and amino groups. These products are formed in the intermediate step in the synthesis of many hetero rings. These compounds are especially used as a starting material in the synthesis of heterostructures such as pyrimidine, pyridine, pyrazole, etc. Therefore, DMF-DMA has been particularly prominent as a reagent in targeted synthesis and designs of many heterocyclic compounds. Herein, the reactions of DMF-DMA reagent with different functional groups are categorized in four classes (methylene, methyl, amino, other groups) and the reactions of obtained enamine and dimethylamino imine compounds are investigated in detail such as nucleophilic addition, intramolecular cyclization or condensation reactions. The synthesis and continuation reactions of the enamine and dimethylamino imine compounds are also examined in terms of experimental conditions and reagents used.
