Abstract
Adenosine deaminase (ADA) inhibitors have been found to have antitumor activities. Here, thirteen potential adenosine deaminase inhibitors 5-amino-1H-pyrazole-4-carboxamide derivatives were designed, synthesized and screened for antitumor activities. Compound 8e exhibited strong growth-inhibitory effects which showed selectivity toward the estrogen receptor positive breast cancer cells (MCF-7) compared to other 5-amino-1H-pyrazole-4-carboxamide derivatives. In addition, it also exhibited appropriate (μM) adenosine deaminase inhibitory potency. Preliminary structure-activity relationships indicated that the incorporation of long chain branching on nitrogen atoms at pyrazole moiety was responsible for their activity.
