In vivo screening and toxicity studies of indolinone incorporated thiosemicarbazone, thiazole and piperidinosulfonyl moieties as anticonvulsant agents.

Bioorg Chem 2021 Aug 24;116:105300. Epub 2021 Aug 24.

Chemistry Department, Faculty of Science (Boys), Al-Azhar University, Cairo, 11884, Egypt. Electronic address:

Based on the biological importance of the thiazole nucleus, we decided to prepare and evaluate the biological activity of some new isatin derivatives containing thiazole moiety. The 5-(piperidin-1-ylsulfonyl)indoline-2,3-dione (1) was prepared and used as a starting material in the synthesis of many isatin derivatives for anticonvulsant evaluation. All the newly synthesized thiazlidino/thiosemicarbazide-indolin-2-one derivatives screened in vivo for their anticonvulsant activity against pentylenetetrazole-induced convulsions in mice. Read More

Methods Mol Biol 2021 ;2388:79-85

Department of Oncology, the First Affiliated Hospital of Anhui Medical University, Hefei, China.

Natural killer T cells (NKT) are abundant in the hepatic sinuses and account for about 20-50% of rat liver lymphocytes. Type I or invariant NKT cells (iNKT) exert a powerful pro-inflammatory effect when activated, while type II NKT cells are more heterogeneous and mainly play an immunomodulatory role. Here we mainly introduced the isolation and characterization methods of human invariant NKT cells. Read More

Toxicological assessment of low-dose bisphenol A, lead and endosulfan combination: chronic toxicity study in male rats.

Environ Sci Pollut Res Int 2021 Sep 15. Epub 2021 Sep 15.

Faculty of Medicine, Department of Medical Biochemistry, Tekirdag Namik Kemal University, Tekirdağ, Turkey.

In the present study, toxic effects, both alone and combined, of bisphenol A (BPA), lead (Pb) and endosulfan (ES) in the low doses were investigated in rat liver and kidney functions. In the study, bisphenol A (BPA), lead (Pb) and endosulfan (ES) were chosen because although they are the chemicals people are most frequently exposed to, no combined toxic effect studies were conducted with these chemicals. Sixty-four male Wistar albino rats were used in the study, and they were randomly divided into eight groups (n = 8 per group); control, BPA (5 mg/kg), Pb (100 ppm), ES (0. Read More

[A protective effect of acetaminophen on ibuprofen-induced small intestinal damage in rats via the suppression of MMP-13].

Nihon Shokakibyo Gakkai Zasshi 2021 ;118(9):840-850

Pharmaceutical Research Laboratories, Research & Development Headquarters, Lion Corporation.

Background & Aims: Capsule endoscopy has revealed that nonsteroidal anti-inflammatory drugs may cause damage not only to the stomach but also to the small intestine, which has become one of the most serious issues in gastroenterology. However, few studies have reported the effect of ibuprofen (IBP), which is widely prescribed worldwide, on the small intestine, and it remains unclear whether IBP can cause small intestinal damage. We have previously shown that acetaminophen (APAP), which is used as an antipyretic/analgesic drug, inhibits IBP-induced gastric damage by suppressing matrix metalloprotease-13 (MMP-13) gene expression.

Obeticholic Acid Decreases Intestinal Content of Enterococcus in Rats With Cirrhosis and Ascites.

Hepatol Commun 2021 Sep 10;5(9):1507-1517. Epub 2021 Jun 10.

Digestive Diseases Section, Yale University, New Haven, CT, USA.

The intestinal microbiome and bacterial translocation (BT), the passage of microorganisms from the gut lumen to mesenteric lymph nodes and other extra-intestinal sites, are main mechanisms implicated in liver injury and further decompensation in patients with cirrhosis. We hypothesized that obeticholic acid (OCA), a semisynthetic bile acid, would change the microbiome composition and reduce bacterial translocation in experimental cirrhosis. Rats with cirrhosis induced by carbon tetrachloride inhalation (a nonseptic model) with ascites present for at least 7 days were randomized to receive a 14-day course of OCA at a dose of 5 mg/kg/day (n = 34) or placebo (n = 34).
