The title compound, [Sn(2)Cl(4)(C(7)H(7))(4)(C(26)H(24)O(2)P(2))], (I), was isolated from the reaction of 1,2-bis(diphenylphosphino)ethane with dibenzyltin(IV) dichloride in the presence of air. The molecules of (I) lie across centres of inversion in space group C2/c and contain five-coordinate Sn atoms. The molecules are linked into chains of rings by a single C-H.pi(arene) hydrogen bond.

Tryptophan participates in important life activities and is involved in various metabolic processes. The indole and aromatic binuclear ring structure in tryptophan can engage in diverse interactions, including π-π, π-alkyl, hydrogen bonding, cation-π, and CH-π interactions with other side chains and protein targets. These interactions offer extensive opportunities for drug development.

Background: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive lethal malignancy with limited options for treatment and a 5-year survival rate of 11% in the United States. As for other types of tumors, such as colorectal cancer, aberrant lipid synthesis and reprogrammed lipid metabolism have been suggested to be associated with PDAC development and progression.
Aim: To identify the possible involvement of lipid metabolism in PDAC by analyzing in tumoral and non-tumoral tissues the expression level of the most relevant genes involved in the long-chain fatty acid (FA) import into cell.

Leydig cells play a crucial role in male reproductive physiology, and their dysfunction is often associated with male infertility. Hypoxia negatively affects the structure and function of Leydig cells. This study aimed to investigate the impact of melatonin on the c-Jun N-terminal kinase (Jnk), P38, and extra-cellular signal-regulated kinases 1 and 2 (Erk1/2) mitogen-activated protein kinase (MAPK) signaling pathways in TM3 mouse Leydig cells under hypoxia induced by cobalt (II) chloride (CoCl).

Background: Many cancer cells exhibit aberrant metabolic reprogramming through abnormal mitochondrial respiration. Protein tyrosine phosphatase mitochondrial 1 (PTPMT1) is a protein tyrosine phosphatase localized to the mitochondria and linked to mitochondrial respiration. However, the expression and role of PTPMT1 in regulating the biological characteristics of small cell lung cancer (SCLC) has not yet been explored.

Sepsis is a systemic infection that significantly causes morbidity and mortality among neonates, which is associated with immature immune response. Variations in the tumor necrosis factor-alpha gene () -308G/A may be linked to neonatal sepsis mortality by modulating interleukins (ILs) involved in the immune response cascade, such as IL-6. The aim of this study was to investigate the association between -308G/A gene variation and IL-6 level with mortality of neonatal sepsis.
