S. Shuto et al., NEW NEPLANOCIN ANALOGS .4. 2-FLUORONEPLANOCIN-A - AN ADENOSINE DEAMINASE-RESISTANT EQUIVALENT OF NEPLANOCIN-A, Chemical and Pharmaceutical Bulletin, 42(8), 1994, pp. 1688-1690
2-Fluoro- and 2-chloroneplanocin A's (2 and 3) were synthesized as an
adenosine deaminase resistant-equivalent of neplanocin A, and evaluate
d for their antitumor and antiviral activities. Of these, 2 was comple
tely resistant to adenosine deaminase and showed more significant anti
