Extraction of alkaline phosphatase (AP) from the tissues of small intestines of mice experimentally infected with the Egyptian strain of S. mansoni before and after oltipraz treatment was carried out. The drug was given in a single oral dose of 500 mg/kg body weight. The results obtained revealed that the drug led to significant reduction in the AP mean level after 30 and 60 days from therapy in comparison to the infected untreated controls. Oltipraz also caused significant reduction in the intestinal AP mean level of the drug control group of mice after 5 and 20 days from drug administration in comparison to normal controls, which might be attributed to the toxic effect of the drug on the intestinal cells.

Early diagnosis is critical for providing a timely window for effective therapy in pulmonary fibrosis (PF); however, achieving this remains a significant challenge. The distinct honeycombing patterns observed in computed tomography (CT) for the primary diagnosis of PF are typically only visible in patients with moderate to severe disease, often leading to missed opportunities for early intervention. In this study, we developed a nanoprobe designed to accumulate at fibroblastic foci and loaded with the CT sensitizer iodide to enable effective early diagnosis of PF.

Background: Morphine effectively relieves severe pain but leads to analgesic tolerance with long-term use.The molecular mechanisms underlying morphine tolerance remain incompletely understood. Existing literature suggests that chemokine CCL2, present in the spinal cord, plays a role in central nervous system inflammation, including neuropathic pain.

Purpose: Oltipraz has various applications, including for treating cancer, liver fibrosis, and cirrhosis. However, its role in regulating metabolic processes, inflammation, oxidative stress, and insulin resistance in STZ-induced T2DM remains unclear. Hence, a comprehensive understanding of how oltipraz ameliorates diabetes, particularly inflammation and oxidative stress, is imperative.

In the context of diabetes, endothelial cells frequently exhibit compromised intercellular junctions and accelerated cellular senescence simultaneously. The precise mechanisms underlying these issues and the identification of effective treatments remain largely undefined. Our findings reveal that human umbilical vein endothelial cells (HUVECs) can counteract senescence and uphold the integrity of intercellular junctions under mildly to moderately elevated glucose levels (10 mM and 15 mM) via two primary mechanisms: i) The acetylation of NRF2 at lysine residues K56, K68, and K52 prevents its ubiquitination, enhancing the transcription of antioxidant genes GST, SOD1, and GPX1.

Oltipraz (OPZ) is a synthetic dithiolethione and is considered a novel activator of nuclear factor E2-related factor 2 (Nrf2). Increasing evidence indicates that Nrf2 protects against cerebral ischemia/reperfusion (I/R) injury by antagonizing ferroptosis and lipid peroxidation. However, the protective effects of OPZ on cerebral I/R injury remain to be elucidated.
