Abstract
The constant demand for eco-friendly methods of synthesizing complex organic compounds inspired researchers to design and develop modern, highly efficient heterogeneous catalytic systems. Herein, In-HCPCP metal-organic framework (SRMIST-1), a heterogeneous Lewis acid catalyst containing less toxic indium and eco-friendly robust cyclotriphosphazene and exhibiting notable chemical and thermal stability, durable catalytic activity, and exceptional reusability was produced through the reaction between indium(III) nitrate hydrate and hexakis(4-carboxylatophenoxy)-cyclotriphosphazene. In the SRMIST-1 structure, secondary building units {InO7} are assembled by a connection of η2- and η1-carboxylic oxo atoms from different HCPCP ligands, forming a three-dimensional network. The occurrence of regularly distributed In(III) sites in SRMIST-1 confers superior reactivity on the catalyst toward the synthesis of 2,3-dihydroquinazolin-4(1H)-ones and 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxides by the cyclization reaction of 2-aminobenzamides and 2-aminobenzenesulphonamides with aldehydes under optimized reaction conditions, respectively. The notable features of this method include broad functional group compatibility, low catalyst loading (1-5 mol %), mild reaction conditions, easy workup procedures, good to excellent reaction yields, ethanol as a green solvent, reusability of the catalyst (five cycles), and economic attractiveness, which is mainly due to sustainability of SRMIST-1 as a reusable green catalyst. Our findings demonstrate that the highly reactive and reusable green catalyst finds widespread applications in medicinal chemistry.

Abstract
We report the atom-economic and sustainable synthesis of biologically important 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxide (DHBD) derivatives from readily available aromatic primary alcohols and 2-aminobenzenesulfonamide catalyzed by nickel(II)-N∧N∧S pincer-type complexes. The synthesized nickel complexes have been well-studied by elemental and spectroscopic (FT-IR, NMR, and HRMS) analyses. The solid-state molecular structure of complex 2 has been authenticated by a single-crystal X-ray diffraction study. Furthermore, a series of 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxide derivatives have been synthesized (24 examples) utilizing a 3 mol % Ni(II) catalyst through acceptorless dehydrogenative coupling of benzyl alcohols with benzenesulfonamide. Gratifyingly, the catalytic protocol is highly selective with the yield up to 93% and produces eco-friendly water/hydrogen gas as byproducts. The control experiments and plausible mechanistic investigations indicate that the coupling of the in situ generated aldehyde with benzenesulfonamide leads to the desired product. In addition, a large-scale synthesis of one of the thiadiazine derivatives unveils the synthetic usefulness of the current methodology.

Abstract
A one-pot, tandem reductive annulation of 2-nitrobenzenesulfonamides with aldehydes to the synthesis of substituted 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxides in the presence of sodium dithionite (Na2S2O4) is reported under mild conditions. The method involves in situ reduction of the nitro group followed by condensation with aldehydes to form an imine, which upon subsequent intramolecular cyclization forms the product under one-pot conditions. The protocol features use of inexpensive Na2S2O4 as the exclusive reagent, appreciable functional group tolerance, broad substrate scope, high product yields, and scalability.

Abstract
Combining solid acid catalysts with enzyme reactions in aqueous environments is challenging because either very acidic conditions inactivate the enzymes, or the solid acid catalyst is neutralized. In this study, Amberlyst-15 encapsulated in polydimethylsiloxane (Amb-15@PDMS) is used to deprotect the lignin depolymerization product G-C2 dioxolane phenol in a buffered system at pH 6.0. This reaction is directly coupled with the biocatalytic reduction of the released homovanillin to homovanillyl alcohol by recombinant horse liver alcohol dehydrogenase, which is subsequently acylated by the promiscuous acyltransferase/hydrolase PestE_I208A_L209F_N288A in a one-pot system. The deprotection catalyzed with Amb-15@PDMS attains up to 97 % conversion. Overall, this cascade enables conversions of up to 57 %.

Abstract
In the present era of the industrial revolution, we all are familiar with ever-increasing environmental pollution released from various chemical processes. Chemical production has had a severe impact on the environment and human health. For the betterment of our environment, the chemical community has turned their interest to developing green, harmless and sustainable synthetic processes. To accomplish these goals of green chemistry, the extraordinary properties of sonication play an important role. It is well known that sonochemistry can make decisive contributions to creating high pressures of almost 1000 atm and very high temperatures in the range of 4500-5000 °C. The implementation of ultrasound in chemical transformations somehow fulfils the measures of green chemistry, as it reduces energy consumption, enhances product selectivity, and uses lesser amounts of hazardous chemicals and solvents. Furthermore, heterocyclic synthesis under ultrasonication offers several environmental and process-related advantages compared with conventional methods. The remarkable contribution of ultrasonics to the development of green and sustainable synthetic routes inspired us to write this article. Herein, we have discussed only some of the various synthetic methodologies developed for the construction of heterocyclic cores under ultrasonic irradiation, accompanied by mechanistic insights. In some cases, a comparison between sonochemical conditions and conventional conditions has also been investigated. We emphasized principally 'up to date' developments on various sono-accelerated chemical transformations comprising aza-Michael, aldol reactions, C-C couplings, oxidation, cycloadditions, multi-component reactions, etc. for the synthesis of heterocycles.

Abstract
A series of indole based novel Schiff bases was designed as potential agonists of 5-HT2C receptor that was supported by docking studies in silico. These compounds were synthesized via Amberlyst-15 catalysed condensation of an appropriate pyrazole based primary amine with the corresponding indole-3-aldehyde under ultrasound irradiation at ambient temperature. A number of target Schiff bases were obtained in good yields (77-87%) under mild conditions within 1 h. Notably, the methodology afforded the corresponding pyrazolo[4,3-d]pyrimidin-7(4H)-one derivatives when the primary amine was replaced by a secondary amine. Several Schiff bases showed agonist activity when tested against human 5-HT2C using luciferase assay in HEK293T cells in vitro. The SAR (Structure-Activity-Relationship) studies suggested that the imine moiety was more favorable over its cyclic form i.e. the corresponding pyrazolopyrimidinone ring. The Schiff bases 3b (EC50 1.8 nM) and 3i (EC50 5.7 nM) were identified as the most active compounds and were comparable with Lorcaserin (EC50 8.5 nM). Also like Lorcaserin, none of these compounds were found to be PAM of 5-HT2C. With ∼24 and ∼150 fold selectivity towards 5-HT2C over 5-HT2A and 5-HT2B respectively the compound 3i that reduced locomotor activity in zebrafish (Danio rerio) larvae model emerged as a promising hit molecule for further study.

Abstract
BACKGROUND The oxazolone class of compounds is known to exert a profound effect on malignant cell proliferation, tumor angiogenesis and /or on the established neoplastic vasculature. Additionally, these compounds are generally known to have a low tendency to interact with DNA which is not common with most of the conventional cytotoxic agents. Thus, this class of compounds is of particular interest for the discovery and development of patient-friendly anticancer agents. OBJECTIVE The initial objective of this study was to synthesize and evaluate 2-substituted 4-arylidene- 5(4H)-oxazolones for their potential anticancer properties. METHODS A simple, mild and non-hazardous synthetic methodology has been developed for the preparation of 2-substituted 4-arylidene-5(4H)-oxazolones. The methodology involved lemon juice mediated condensation of N-acyl glycine derivatives including hippuric acid with arylaldehydes in PEG-400 under ultrasound irradiation. All the synthesized compounds were screened via an MTT assay for their potential cytotoxic properties in vitro using the cancerous cell lines e.g. K562 (human chronic myeloid leukemia), Colo-205 (human colon carcinoma), and A549 (human lung carcinoma) and a non-cancerous HEK293 (human embryonic kidney) cell line. RESULTS Compounds 3a, 3c and 3i showed promising growth inhibition against A549 cell line but no significant effects on HEK293 cell line, indicating their selectivity towards cancer cells. Moreover, their IC50 values suggested that all these compounds were comparable to the reference drug doxorubicin indicating their potential against lung cancer. CONCLUSION The 4-arylidene-5(4H)-oxazolone framework presented here could be a new template for the design and discovery of potential anticancer agents especially for lung cancer.

Abstract
BACKGROUND Compounds containing the quinazoline-4(3H)-one framework constitute an important class of fused N-heterocycles that are found in more than 200 naturally occurring alkaloids. These compounds also show a diverse range of pharmacological activities including antitumor properties. This prompted us to explore a series of quinazolin-4-(3H)-one derivatives having no substituent at C-2 as potential cytotoxic agents. OBJECTIVE The objective of this study was to synthesize and evaluate 3-substituted quinazolin-4(3H)-one derivatives for their potential cytotoxic properties. METHODS A convenient method has been developed for the rapid synthesis of this class of compounds under a mild and non-hazardous reaction condition in good yields. The methodology involved a three-component reaction employing isatoic anhydride, amines and glyoxylic acid as reactants in the presence of lemon juice in PEG- 400 at room temperature (25-30ºC) under ultrasound irradiation. All the synthesized compounds were screened via an MTT assay for their potential cytotoxic properties in vitro using the cancerous cell lines e.g. A549, A2780, HepG2, K562, MCF-7 and HCT-116 and a non-cancerous HEK293 cell line. RESULTS Several compounds such as 3a, 3b, 3d, 3e and 3f showed promising growth inhibition against these cancer cell lines but no significant effects on HEK293 cell line. The IC50 values of these compounds were comparable to doxorubicin whereas 3f significantly induced apoptosis in MCF-7 cells that also was comparable to doxorubicin. CONCLUSION An ultrasound-assisted MCR facilitated by lemon juice has been developed to synthesize 3- substituted quinazolin-4(3H)-one derivatives that could act as potential anticancer agents.

Abstract
BACKGROUND The 2-amino 1,3,4-thiadiazole framework has attracted considerable interest because of its prevalence in compounds possessing a wide range of pharmacological properties including anticancer/antitumor activities. Though a number of methods have been reported for the synthesis of this class of compounds, some of them are not straightforward, inexpensive and environmentally friendly. OBJECTIVE To synthesize 2-amino-1,3,4-thiadiazole derivatives that could act as potential anticancer agents. METHODS The use of lemon juice as an inexpensive and readily available biocatalyst was explored in the synthesis of 2-amino 1,3,4-thiadiazole derivatives. Accordingly, a convenient method has been developed for the rapid synthesis of this class of compounds under a mild and non-hazardous reaction condition in good yields. The methodology involved the reaction of various acid hydrazides with TMSNCS in the presence of lemon juice in PEG-400 at room temperature (25-30ºC) under ultrasound irradiation. These compounds were assessed for their cytotoxic properties against two different metastatic breast cancer cell lines e.g., MDAMB-231 and MCF-7 and subsequently against SIRT1. RESULTS The 2-amino 1,3,4-thiadiazole derivatives 3a, 3i, 3j and 3l showed promising growth inhibition of MDAMB- 231 and MCF-7 cell lines and SIRT1 inhibition in vitro. Indeed, 3i was found to be a potent inhibitor of SIRT1. CONCLUSION An ultrasound-assisted method facilitated by lemon juice has been developed to synthesize 2-amino- 1,3,4-thiadiazole derivatives that could act as potential anticancer agents.

Abstract
An efficient green protocol for the synthesis of complex hybrid heterocycles containing [1,6]-naphthyridine and coumarin/pyrazole moieties was established, involving an intramolecular [4 + 2] hetero Diels-Alder reaction as the key step. The biologically significant 12,13-dihydro-6H-benzo[h]chromeno[3,4-b][1,6]naphthyridin-6-ones and 6,10-dihydro-5H-benzo[h]pyrazolo[3,4-b][1,6]naphthyridines were synthesized starting from 2-(N-propargylamino)-arylaldehydes and 3-aminocoumarins or 3-methyl-1-aryl-1H-pyrazol-5-amines in the presence of an Amberlyst-15 catalyst in PEG-200 in good yields. The easy access to diverse complex molecules in a single operation from readily available starting materials, a commercially available, transition metal-free and recyclable catalyst, the use of a green solvent, a very high atom economy and the release of water as the only side product are the highlights of this protocol.

Abstract
BACKGROUND A non-hazardous synthetic methodology has been developed for the preparation of compounds based on indolofuroquinoxaline framework. Lemon juice that is known to play the role of a biocatalyst in various organic reactions was used for this purpose. METHOD A number of indolofuroquinoxaline derivatives were prepared via the lemon juice mediated condensation of methyl 2-(2-chloro-1H-indol-3-yl)-2-oxoacetate or its N-alkyl derivatives with 1,2- diamines under ultrasound irradiation. All the synthesized compounds were screened via an MTT assay for their potential anticancer properties in vitro using a number of cancer cell lines including MDA-MB 231, and MCF7, K562, Colo-205 and IMR-32 and the non-cancerous HEK293 cell line. Compounds 3a, 3b and 3c showed promising growth inhibition against K562, MDA-MB 231 and MCF7 cell lines but no significant effects on HEK293 cell line suggesting their selectivity towards cancer cells. RESULTS AND CONCLUSION Moreover, according to their IC50 values, all these compounds appeared to be relatively more potent towards K562 cell line over MDA-MB 231 and MCF7 cell lines indicating their potential against leukemia.

Abstract
Transient receptor potential melastatin 2 (TRPM2), a Ca2+-permeable cationic channel, plays critical roles in insulin release, cytokine production, body temperature regulation and cell death as a reactive oxygen species (ROS) and temperature sensor. However, few TRPM2 inhibitors have been reported, especially TRP-subtype selective inhibitors, which hampers the investigation and validation of TRPM2 as a drug target. To discover novel TRPM2 inhibitors, 3D similarity-based virtual screening method was employed, by which 2,3-dihydroquinazolin-4(1H)-one derivative H1 was identified as a TRPM2 inhibitor. A series of novel 2,3-dihydroquinazolin-4(1H)-one derivatives were subsequently synthesized and characterized. Their inhibitory activities against the TRPM2 channel were evaluated by calcium imaging and electrophysiology approaches. Some of the compounds exhibited significant inhibitory activity, especially D9 which showed an IC50 of 3.7 μM against TRPM2 and did not affect the TRPM8 channel. The summarized structure-activity relationship (SAR) provides valuable insights for further development of specific TRPM2 targeted inhibitors.
