Using of Di- and Triorganotin(IV) complexes as photostabilizer for poly(vinyl chloride)

      Four organotin complexes containing furosemide as a ligand (L), Ph3SnL, Me2SnL2, Bu2SnOHL and Bu2SnL2, were synthesized in alcoholic medium.These complexes are:

Dimethyltin di-[4-hloro-2-(furan-2-ylmethylamino)-5-sulfamoylbenzoic acid], Me2SnL2

Dibutyltin di-[ 4-chloro-2-(furan-2-ylmethylamino)-5-sulfamoylbenzoic acid], Bu2SnL2

Dibutyltin hydroxy [4-chloro-2-(furan-2-ylmethylamino)-5-sulfamoylbenzoic acid], Bu2SnOHL

Bioactive Sphingolipids and metabolizing enzymes in patients with benign prostate hyperplasia and malignant prostate cancer

       Bioactive Sphingolipids an important molecules of structural and signaling lipids. In this study was highlight on new biomarkers uses to investigate prostate cancer by using new method HPLC fluorescence detector to measure concentration and activity enzymes sphingosine-1-phosphate lyase enzyme (SPL) and Acid Ceramidase enzyme (AC) by used new material (BODIPY) aromatic structural is binding with enzymes and give fluorophore product sensitive by HPLC fluorescence detector in patients have BPH and PC in serum and tissue and comparing with healthy men as (control).
