Spring 2008 Seminars

February 7, 2008
Dr. Andy Lichtman , Nassau County Department of Health
Trace Analysis of Environmental Toxins
Monitoring of organic contaminants in Nassau County drinking water is the primary responsibility of the trace organics laboratory of the Nassau County Department of Health. Employing techniques such as GC-MS, a large number of compounds can be analyzed. Some results will be presented.
Location: Hofstra University
Chemistry/Physics Building, Lister Auditorium

Dr. Sandra Reznik , St. John's University
The Role of Endothelien I in Preterm Labor and its Inhibition by Novel 1,3,6-Trisubstituted 4-Quinolone ET-1
Preterm birth occurs in 12% of deliveries and accounts for half of long-term neurological morbidity and 60-80% of perinatal mortality. The role played by ET-1 in preterm birth, based on biochemical, pharmacologic and molecular genetics approaches, will be presented. Evidence will be shown demonstrating that "knockdown" of mRNA encoding ECE-1 (the enzyme that synthesizes ET-1 in vivo) results in control of preterm birth. Our findings have led to the synthesis of various putative ET receptor antagonists. Data will be presented showing that one of these novel compounds, HJP279, controls preterm birth in mice. The compounds are useful both in dissecting the molecular mechanism of preterm birth as well as potentially impacting on disorders ranging from acute lung injury to cerebral malaria.

The Ansa-Effect in Permethylmetallocene Chemistry
On many occasions, the reactivity of ansa-bridged metallocene complexes was different from that of its non-ansa analogues. For example, ansa-bridged permethylmolybdenocene dihydride (Cp^#₂MoH₂) showed intermolecular C-H or C-C activation, while pentamethylmolybdenocene (Cp^*₂MoH₂) preferred the intramolecular C-H activation to give a tuck-in complex. Also the reductive elimination of H₂ in the ansa-bridged permethyltantalocene trihydride complex (Cp^#₂TaH₃) was 1000-2000 times faster than in the pentamethyltantalocene trihydride complex (Cp^*₂TaH₃). What makes the difference? The influence of ansa bridges on the chemistry of metallocene complexes will be discussed and compared to non-ansa bridged metallocene complexes.
