    BACKGROUND: Recent reports have revealed that nephropathy leading to kidney injury (KI) is a prevalent complication of COVID-19 and is linked to high mortality and morbidity in diabetes mellitus type II (DM-T-II) patients. This systematic literature review and meta-analysis aimed to critically analyze existing studies and evidence on the impact of COVID-19 on nephropathy and kidney injury in diabetes mellitus type II (DM-T-II) patients.

    METHOD: A systematic search was conducted in the Web of Science (WoS), PubMed and Cochrane databases for relevant studies published between March 2020 and July 2023. To ensure the integrity of the systematic literature review and meta-analysis, observational studies that specifically reported post-COVID-19 kidney injury in DM-T2 patients were included, whereas we did not include articles in the press, meta-analyses, case reports, case series, Diabetes Type-I articles or non-English papers. The primary outcome was kidney injury in patients with type II diabetes after contracting COVID-19. The protocol for this study was published on PROSPERO (registration number CRD42023413887).

    RESULTS: Initially, 6,339 articles were included in the search, from which only 6 observational studies were selected by following the 2020 PRISMA statement. The quality of the evidence was assessed by a tool provided by the National Institutes of Health (observational studies). The total number of participants included in the studies was 14,723. Our systematic literature review and meta-analysis provide compelling evidence that kidney injury is a prevalent complication of COVID-19 infection in the type II diabetes population, with a pooled odds ratio of 2.27 (95% CI: 2.05-2.51; p

    Synthesis of 2,5-bisarylthiophenes was accomplished by sequential Suzuki cross coupling reaction of 2-bromo-5-chloro thiophenes. Density functional theory (DFT) studies were carried out at the B3LYP/6-31G(d, p) level of theory to compare the geometric parameters of 2,5-bisarylthiophenes with those from X-ray diffraction results. The synthesized compounds are screened for in vitro bacteria scavenging abilities. At the concentration of 50 and 100 μg/mL, compounds 2b, 2c, 2d, 3c, and 3f with IC50-values of 51.4, 52.10, 58.0, 56.2, and 56.5 μg/mL respectively, were found most potent against E. coli. Among all the synthesized compounds 2a, 2d, 3c, and 3e with the least values of IC50 77, 76.26, 79.13 μg/mL respectively showed significant antioxidant activities. Almost all of the compounds showed good antibacterial activity against Escherichia coli, whereas 2-chloro-5-(4-methoxyphenyl) thiophene (2b) was found most active among all synthesized compound with an IC50 value of 51.4 μg/mL. All of the synthesized compounds were screened for nitric oxide scavenging activity as well. Frontier molecular orbitals (FMOs) and molecular electrostatic potentials of the target compounds were also studied theoretically to account for their relative reactivity.

    The undertaken research was initiated by transforming 2-(1H-Indol-3-yl)acetic acid (1) in catalytic amount of sulfuric acid and ethanol to ethyl 2-(1H-Indol-3-yl)acetate (2), which was then reacted with hydrazine monohydrate in methanol to form 2-(1H-Indol-3-yl)acetohydrazide (3). Further, The reaction scheme was designed into two pathways where, first pathway involved The reaction of 3 with substituted aromatic aldehydes (4a-o) in methanol with few drops of glacial acetic acid to generate 2-(1H-Indol-3-yl)-N'-[(un)substitutedphenylmethylidene]acetohydrazides (5a-o) and in second pathway 3 was reacted with acyl halides (6a-e) in basic aqueous medium (pH 9-10) to afford 2-(1H-Indol-3-yl)-N'-[(un)substitutedbenzoyl/2-thienylcarbonyl]acetohydrazides (7a-e). All The synthesized derivatives were characterized by IR, EI-MS and 1H-NMR spectral techniques and evaluated for their anti-bacterial potentials against Gram positive and Gram negative bacterial strains and it was found that compounds 7a-d exhibited antibacterial activities very close to standard Ciprofloxacin. The synthesized derivatives demonstrated moderate to weak anti-enzymatic potential against α-Glucosidase and Butyrylcholinesterase (BChE) where, compounds 7c and 5c exhibited comparatively better inhibition against these enzymes respectively. Compounds 7a, 7d and 7e showed excellent anti-enzymatic potentials against Lipoxygenase (LOX) and their IC50 values were much lower than the reference standard Baicalein. Enzyme inhibitory activities were also supported by computational docking results. Compounds 5c, 7a, 7b and 7c also showed low values of % hemolytic activity as well, showing that these molecules were not toxic, indicating that these molecules can be utilized as potential therapeutic agents against inflammatory ailments.
