Background: Triazine ring is a prominent structural motif found in some azanucleosides whose efficiency improved many times in the research area of antitumor agents.
Objective: In this study, we have designed and synthesized novel 2-[(5,6-diphenyl-1,2,4-triazin-3-yl)thio]-N-(6- substituted benzo/(thiazol)-2-yl)acetamide (2a-d, 3a-f) derivatives using 1,2,4-triazine core along with two important heterocyles, thiazole and benzothiazole rings.
Method: The acquired ten final compounds were screened to investigate their antitumor activity against lung adenocarcinoma cell line, A549 and mouse fibroblast cell line, NIH/3T3. Five compounds with higher antiproliferative activity have been further studied to evaluate whether the cell death due to necrosis or apoptosis using flow cytometry.
Results And Conclusion: Compound 3b bearing 6-methylbenzothiazole moiety has been established as the most active antitumor compound with a selective profile and higher apoptotic cell level. All final componds were also screened against acetylcholine/butyrylcholinesterase enzymes to state their anticholinesterase activity.

A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B'α and B'β in pollen wall formation. The b'aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release.

The current study was deployed to evaluate the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and miR-155, along with the inflammatory markers, TNFα and IL-6, and the adhesion molecule, cluster of differentiation 106 (CD106), in Behçet's disease (BD) pathogenesis. The study also assessed MALAT1/miR-155 as promising diagnostic and prognostic biomarkers for BD. The current retrospective case-control study included 74 Egyptian BD patients and 50 age and sex-matched controls.

Purpose Of Review: To outline the latest discoveries regarding the utility and reliability of serum biomarkers in idiopathic recurrent acute pericarditis (IRAP), considering recent findings on its pathogenesis. The study highlights the predictive role of these biomarkers in potential short- (cardiac tamponade, recurrences) and long-term complications (constrictive pericarditis, death).
Recent Findings: The pathogenesis of pericarditis has been better defined in recent years, focusing on the autoinflammatory pathway.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.
