The reactions of 1,3,5-triaminobenzene derivatives with 2,3,4-trinitrothiophene and 2-bromo-3,4,5-trinitrothiophene gave new all-conjugated compounds bearing both an electron-withdrawing and an electron-donor moiety on the same unit. The reactions with 2,3,4-trinitrothiophene offered evidence, by NMR spectroscopy at low temperature, of the formation of new labile Wheland-Meisenheimer intermedia...

The Richman-Atkins cyclization remains one of the most widely used methods for the preparation of macrocyclic polyamines. The use of beta-trimethylsilylethanesulfonamides (SES-sulfonamides) for the preparation of polyazamacrocyclic compounds is described. This expands existing Richman-Atkins sulfonamide macrocyclization methodology, and it successfully enables preparation of labile polyaza[n](1...

congenital factor x deficiency is a rare autosomal recessive bleeding disorder that presents with variable bleeding tendency and prolonged coagulation tests, prothrombin time, and partial thromboplastin time. thromboembolic events have not been reported in patients with factor x deficiency yet. herein, we report a patient with factor x deficiency who had recurrent venous thromboembolic events.

cerebral vein thrombosis (cvt) is an infrequent condition with a large variety of causes that can lead to serious disabilities. however, in 20% to 35% of cases, no cause is found. in this study we evaluated the hereditary (p & c proteins, antithrombin, mutation of prothrombin g20210a and factor v leiden), other risk factors (hyperhomocycteinemia, factor viii, acl-ab, apl-ab, and ocp) and clinic...

A series of water-soluble (NHC)Pt(0)(dvtms) and (NHC)Pt(0)(AE) complexes containing different sulfonated NHC ligands (dvtms = divinyltetramethyldisiloxane and AE = diallyl ether) are reported. The dvtms compounds have been found to be quite robust and to display some conformational rigidity, whereas their AE counterparts are less stable and more flexible. The catalytic evaluation of these compl...

BACKGROUND Factor V deficiency is a rare autosomal recessive coagulation disorder. Awareness of presenting features and management is important to avoid bleeding complications associated with mortality and neurodisability. CASE PRESENTATION A 6-day-old Pakistani boy was admitted with bleeding from the left nipple. His parents were first cousins. A coagulation screen showed a prothrombin time ...

Studies were performed on a FrenchCanadian family afflicted with a bleeding disorder exhibiting an autosomal dominant inheritance pattern and a severe bleeding diathesis after trauma. Clinical laboratory coagulation tests were unimpressive; the only persistent abnormalities include mild thrombocytopenia and moderately reduced Factor V clotting activities. Some individuals had prolonged Stypven ...

BACKGROUND The thrombin-generation assay has a variety of clinical uses, including diagnosis of thromboembolism-related disease, and particular profiles are associated with thrombophilic risk factors. The aim of this study was to evaluate the use of this assay in screening and identifying patients who require specific thrombophilic testing. METHODS We used a 2-step approach to perform specifi...
