(PhysOrg.com) -- The name is anything but exciting - and yet the compound known as PDC113.824 may have a very exciting future. It is the precursor of a drug which may one day provide effective treatment for the common and very serious problem of preterm birth. "We are excited about this compound because it belongs to a new class of drug, and because it has potential to prevent premature labour, possibly with fewer side effects than current treatments," says MUHC researcher in endocrinology Dr. Stephane Laporte, corresponding author of a recent study of PDC113.824, published in collaboration with Université de Montreal (UdeM) and other Quebec research centres, in the Journal of Biological Chemistry. http://phys.org/news204390950.html Chemistry Wed, 22 Sep 2010 16:30:02 EST news204390950 Ewing sarcoma is the second most common type of primary bone cancer seen in children and young adults. Patients with relapsed or refractory Ewing sarcoma have a poor outcome with conventional therapies. Cytarabine decreases the levels of a certain key protein in Ewing sarcoma cells and has demonstrated preclinical activity against Ewing sarcoma cell lines in the laboratory. Treatment of Ewing sarcoma that relapses is difficult. A new study published in Pediatric Blood & Cancer evaluated a phase II clinical trial of a potential new treatment approach for relapsed Ewing sarcoma using cytarabine. http://phys.org/news145558218.html Medicine & Health Mon, 10 Nov 2008 16:50:18 EST news145558218
