The first incidence of corona virus was reported in China in December of 2019, and the virus quickly spread over the world, eventually being designated a pandemic in March of 2020. It has had a disastrous impact on the global healthcare system. Virus has claimed the lives of 5,298,933 people through December 2021. As a result of the pandemic, there was a boost of research into diagnostic and therapeutic methods to infection. Gradually, the world has discovered new vaccine candidates and medicinal repurposing strategies that have a significant influence on mortality, by which there has been a drop-in death rates over the world since July, 2021. Many patients, particularly those who have been hospitalized due to a viral infection, experience complications beyond discharge that have a significant influence on their lives. Post COVID-19 complications are problems that last longer than 3-4 weeks following a viral infection. There is currently no specific treatment accessible for post COVID-19 problems because whatever medications are available or repurposed are limited to disease prophylaxis and therapeutics. As a result, we're looking for a remedy employing natural substances using the In-Silico technique (molecular docking) and recent research from reputable journals. Allicin, Berberine, Epigallocatechin, Rosmarinic acid and Withaferin-A were docked against ACE (PDB ID: 1O8A), IL-6 (PDB ID: 1ALU), NADPH Oxidase (PDB ID: 2CDU) and TNF- α (PDB ID: 2AZ5) using Autodock.

In this study, methoxy benzoin compounds (1-10) were synthesized from the corresponding aromatic aldehydes based on a screening of biological activity. Oxidation and reduction of benzoins (1-10) yielded the corresponding benzils (11-20) and stilbenoids (21-29), respectively. The enzyme inhibition, antimicrobial, and antioxidant activities of 1-29 were evaluated. 1, 14, 19, and 28 against α-amylase, 15 and 19 against α-glucosidase, 2, 4, 14, 18, 25 and 26 against tyrosinase, 2, 7, and 23 against AChE, and 7, and 13 against BChE showed similar activity to the standard used. Among the methoxy benzoin derivatives, 4 proved to be the most active compound against E.coli, Y.pseudotuberculosis, M. smegmatis, and C.albicans in the range of 41-82 µg/mL MIC values. All benzil derivatives displayed bioactivity against M.smegmatis and C. albicans. Compounds 18 and 11 were found to be most effective against M.smegmatis, and compounds 11 and 17 were found to be the most effective against C.albicans. All stilbenoid type compounds showed selective activity against B.cereus. Compounds 21 and 22 were the most effective stilbenoid compounds against M. smegmatis. Benzoins (1-10) were the most effective antioxidants among all three groups compared to the tested methods, which can be attributed to the free hydroxyl at the benzylic position. As a result, the change of carbon skeleton and substitution at different positions of synthesized organic compounds also caused the variation of biological activity.

Microwave-assisted one-pot synthesis of tetrahydrobenzo[b]pyrans in the presence of WEWFPA and their electrochemical studies

Org. Commun. (2022) in press ; 1 - 19
by Kantharaju Kamanna , Krishnappa B Badiger and Lokesh Koodlur Sannegowda

IThe present work described one-pot three-component synthesis of tetrahydro benzo[b]pyran derivatives using Water Extract of Watermelon Fruit Peel Ash (WEWFPA) as a inexpensive grener catalyst. The title compounds were synthesized via the condensation reaction of aromatic aldehyde, dimedone, and ethyl cyanoacetate under microwave irradiation in agro-waste solvent medium and ethanol as a co-solvent. The developed method is simple, rapidity, high yields, pure, low cost, mild reaction condition, evading use of toxic metals and solvent, and the catalyst reusability are the main advantages. The resulting products were isolated by simple workup and recrystallization gave pure compounds. Further, the oxidation and reduction potential of the selected tetrahydrobenzo[b]pyran derivatives were studied using cyclic voltammetry.

Nano TiO2.SiO2 catalyzed, microwave assisted synthesis of new α-aminophosphonates as potential anti-diabetic agents: In silico ADMET and molecular docking study

Using microwave irradiation, an effective and greener method for the synthesis of α-aminophosphonates via Kabachinic-Fields reaction in a solvent-free environment is devised. An in silico ADMET and molecular docking analysis was performed on all of the compounds to get insight into their drug likeliness behaviour as well as their capacity to block the enzyme α-amylase (PDB ID: 3IJ8). The compounds with the highest binding affinity and pharmacokinetic properties were developed. The newly created compounds were spectroscopically examined to establish their structure, and all of them were tested for in vitro α-amylase inhibitory action. The compounds 7j (IC50: 99.9±0.3 μg/mL) and 7e (IC50: 102.0±0.7 μg/mL) showed stronger inhibitory efficacy than acarbose, the reference medication. The compounds 7g (IC50, 106.7±0.4 μg/mL), 7d (IC50, 108.4±0.3 μg/mL), 7h (IC50, 115.0±0.4 μg/mL), and 7f (IC50, 119.2±0.4 μg/mL) have shown to inhibit the target enzyme significantly.When compared to the reference drug, Acarbose (IC50, 102.6±0.8 μg/mL), all of the remaining compounds showed modest to good inhibition with IC50 values ranging from 125.6±0.6 to 152.7±0.2 μg/mL. The findings revealed that the vast majority of these drugs have strong α-amylase inhibitory action.
