Background: Cancer is one of the diseases with high mortality rate recorded each year across the world. Its mainstay treatment is chemotherapy although they are largely toxic, causing severe adverse reactions including cardiotoxicity, nephrotoxicity and genotoxicity. Cardiotoxicity is unique to certain chemotherapeutic agents and occur via several mechanisms. It has been hypothesized that co-administration of natural products which may be cardioprotectant, together with chemotherapy can alleviate cardiotoxicity-induced by chemotherapy. Objectives: This review aimed to provide a brief information about the protective effect of natural products against chemotherapy-induced cardiotoxicity Methods: To complete this review, relevant literatures were searched from several scientific databases including Google, Google Scholar, Scopus, Web of Science and Pubmed. Results: In this paper, we have reviewed ten natural products (curcumin, mangiferin, naringenin, quercetin, 6-gingerol, lycopene, resveratrol, apigenin, proanthocyanidins and indole-3-carbinol), which have major influences in attenuating chemotherapy-drug induced cardiotoxicity. Apart from the cardioprotective effects, they tend to confer some synergistic effects with chemotherapeutic agents and therefore have the potential to be used as an adjunct. Conclusion: Though a panel of natural products demonstrate protective effects against cardiotoxicity in cells and animal models, their therapeutic potentials for clinical needs further investigation.

Background: Terminalia spp. are characterised by their high antioxidant capacities and many have anticancer activity. This study examines the anti-proliferative activity of T. carpentariae leaf and T. grandiflora leaf, fruit and nut extracts against Caco-2 and HeLa carcinoma proliferation. Materials and Methods: Powdered T. carpentariae leaf and T. grandiflora leaf, fruit and nut were extracted and tested for anti-proliferative activity against Caco-2 and HeLa cancer cell lines using colorimetric cell proliferation assays. Toxicity was evaluated using an Artemia franciscana nauplii bioassay. The extract with the most potent anti-proliferative activity was examined using GCMS analysis and triterpenoid compounds were identified by comparison with a compound database. Results: T. carpentariae leaf and T. grandiflora leaf, fruit and nut extracts displayed potent anti-proliferative activity against Caco-2 and HeLa carcinoma cells. The methanolic T. grandiflora leaf extract was particularly effective at blocking the proliferation of the colorectal carcinoma Caco-2 (IC50 = 372 \μg/mL). The methanol T. carpentariae and T. grandiflora leaf extracts were similarly potent inhibitors of HeLa cervical cancer cell proliferation with IC50 values of 864 and 833 \μg/mL respectively. The methanolic T. grandiflora fruit and nut extracts, as well as all aqueous and ethyl acetate extracts, were moderate to good inhibitors of carcinoma proliferation. In contrast, chloroform and hexane extracts were generally devoid of anti-proliferative activity. The methanolic T. grandiflora extracts displayed low toxicity in the Artemia nauplii bioassay. All other extracts were non-toxic. GC-MS analysis of the methanolic T. grandiflora leaf extract identified 3 lanostane and 2 pentacyclic triterpenoids. Conclusion: The low toxicity and anti-proliferative activity observed with the T. carpentariae and T. grandiflora extracts against Caco-2 and HeLa indicate their potential for the prevention and treatment of some cancers.

Cancer is actually a group of many related diseases that all have to do with cells. Cancer cells are characterized by unregulated growth, as well as insufficient and inappropriate vascular supply. Moreover, a core of cells was subjected to micro environmental stress conditions, and has decreased apoptotic potential through genetic alterations, thereby resulting in resistance to apoptosis. Cancer is one of the major causes of death worldwide where the number of cancer patients is in continuous rise. Cancer is a major public problem whose estimated worldwide new incidence is about 6 million cases per year. It is the second major cause of deaths after cardiovascular diseases. Chemotherapy remains the principal mode of treatment for various cancers. A number of synthetic anticancer drugs are available in practice, but the side effects and the drug interactions are major drawbacks in its clinical utility. Most of the currently used chemotherapy drugs for cancers are known to develop resistance, exhibit non-selective toxicity against normal cells and restrict by dose-limiting side effects. Hence, cancer treatment and development of drugs for this disease remains a major clinical challenge. On the other hand, plants are an exceptionally viable source of biologically active natural products which may serve as commercially significant entities in themselves or which may provide lead structures for the development of modified derivatives possessing enhanced activity and/or reduced toxicity in traeatment of cancer. Herbal medicines are now attracting attention as potential sources of anticancer agents and are widely used due to availability of the materials, affordability, relatively cheap and little or no side effects, wide applicability and therapeutic efficacy which in turn has accelerated the scientific research. For these reasons, World Health Organization (WHO) supports the use of traditional medicines which are efficacious and non toxic. In this review we have summarized few plants having anticancer activity.
