Introduction . This work is devoted to the intestinal permeability study of 7-(2-chlorophenyl)-4-(4-methyl-1,3-thiazol-5-yl)-4,6,7,8-tetrahydroquinoline-2,5(1H,3H)-dione – innovative biologically active substance with TRPA1 antagonist activity. The phenyltetrahydroquinolinedione derivative a promising analgesic and anti-inflammatory drug. To develop dosage form this new substance, it necessary ...

BACKGROUND Intestinal hyper-permeability plays a critical role in the etiopathogenesis of inflammatory bowel disease (IBD) by affecting the penetration of pathogens, toxic compounds and macromolecules. 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], the active form of vitamin D, has been shown to be an important regulator of IBD and recent epidemiology suggests that patients with IBD have an impaired v...

Objective:In vivo studies suggest that intestinal barrier integrity is dependent on mitochondrial ATP production. Here, we aim to provide mechanistic support, using an in vitro model mimicking the oxidative in vivo situation. Methods: Human Caco-2 cells were cultured for 10 days in culture flasks or for 14 days on transwell inserts in either glucose-containing or galactose-containing medium. Mi...

BACKGROUND Dapsone is described as being active against Mycobacterium leprae, hence its role in the treatment of leprosy and related pathologies. Despite its therapeutic potential, the low solubility of dapsone in water results in low bioavailability and high microbial resistance. Nanoemulsions are pharmaceutical delivery systems derived from micellar solutions with a good capacity for improvin...

Vitamin D is an essential nutrient with important immunomodulatory properties. As a fat-soluble compound, (and its D3 form) immiscible water, which presents challenges to absorption. In in vitro setting, the current study characterizes novel micellar formulations of designed improve Techniques used evaluate and compare against non-micellar formula include following: cryo-SEM determine morpholog...

Background: Numerous molecules in Papaveraceae family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few cases. Objective: Numerous molecules in this family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a fe...

Introduction: Efforts are made to identify the new potential components such as anticancer drugs. Medicinal plants belonging to Euphorbia genus are widely studied with promising effects. The current study aimed at investigating the effect of ethanolic extract of the root of E. tehranica, grown in Iran, on Caco-2 human colorectal cancer cell-line. Methods: The Caco-2 cells were treated with dif...
