Cancer Gene Therapy
New cancer gene therapy study findings have been reported by A.E.A. Hassan and colleagues
November 5th, 2009
According to a study from the United States, "Metalation of 6-methyl-9-(tetrahydro-2H-pyran-2-yl)purine (10) with lithiating agents of varying basicities such as n-BuLi and LiHMDS in THF at - 78 degrees C resulted in metalation at both of the 6-CH3 moiety and the 8-CH position, irrespective of the molar equivalence of the base. On the other hand, a regioselective metalation at the 6-CH3 moiety of 10 was observed with NaHMDS or KHMDS, under similar conditions." "Treatment of the potassium salts of 10 and of the protected riboside derivative 6-methyl-9-(beta-D-2,3,5-tri-O-tert-butyldimethylsilylribofuranosyl)purine (22) with N-fluorobenzenesulfonamide (NFSI) at - 78...
