Abstract
The ever-increasing occurrence of cancer and the severe side effects and
limited efficacy of current cancer chemotherapy based on chemical drugs
shift the attention toward drugs of plant origin. The Cactaceae family
comprises more than 1500 species, but until recently only a few of them have
been tested for their chemopreventive and anticancer attributes, leaving a
wide unexplored area still waiting for researchers to investigate.
Considering this fact, and also the promising results obtained with the
relatively few plants of this family already tested, it should justly be
expected that some plants of the Cactaceae family yet unexplored might
possess outstanding anticancer attributes, exceeding those displayed by the
plants already tested. This review presents in vitro and in
vivo experimental evidence on cancer chemopreventive and therapeutic
potential of bioactive phytoconstituents and extracts derived from cactus
plants. It also examines the underlying biochemical and molecular mechanisms
involved in the antineoplastic effects of plants of the Cactaceae family.
Current limitation and future directions of research towards effective use
of cacti to develop efficient and side effect-free future cancer-preventive
and anticancer drugs are also discussed.
