Abstract

The incidences of cancer are continuously increasing worldwide, affecting life of millions of people. Several factors associated with the internal and external environment are responsible for this deadly disease. The key internal determinants like abnormal hormonal regulation, genetic mutations and external determinants such as lifestyle and occupational factors enhances onset of cancer. From the ancient time, plants were remained as the most trusted source of medicine for the treatment of diverse disease conditions. Extensive studies have been performed for the discovery of effective anticancer agent from the plant and still it is going on. Pentacyclic triterpenoids are biologically active phytochemicals having a different range of activities such as anti-inflammatory, hepatoprotective, anti-hypertensive, antiulcerogenic and anti-tumor. These compounds generally contain ursane, oleanane, lupane and friedelane as a chief skeleton of pentacyclic triterpenoids which are generally present in higher plants. Isoprene unit, phytochemical, with good antitumor/anticancer activity is required for the biosynthesis of pentacyclic triterpenoids. Mechanisms such as cytotoxicity, DNA polymerase inhibition, regulation of apoptosis, change in signal transductions, interfere with angiogenesis and dedifferentiation, antiproliferative activity and metastasis inhibition are might be responsible for their anticancer effect. Present review spotlights diverse targets, mechanisms and pathways of pentacyclic triterpenoids responsible for anticancer effect.

Keywords: anti-angiogenic; antiproliferative; apoptosis; cancer; isoprene; pentacyclic triterpenoids.

Extrinsic Pathway (Death receptor pathway) is activated when a tumor necrosis factor (TNF) receptor is stimulated by particular death ligands that recruits proteins (adaptor protein) and activate initiator caspases (caspases 8) which further activate effector caspases (caspase 3). Whereas, intrinsic pathway (mitochondrial pathway) activate other signals, such as being DNA damage which cannot be repaired, the p53 (tumor suppressor gene) protein activates a subpathway that leads to release of cytochrome c from the mitochondrion, with successive participation of the apoptosome [a complex of procaspase 9, cytochrome c and apoptic activating protease factor-1 (Apaf-1)], and activation of caspasen 3 (initiator caspases) and caspase 9. R→ Receptor for growth factors, trophic factor and cell to cell contact factor (Continuous stimulation to this receptor is necessary for cell survival). Fas ligand→Trans membrane receptor that induce apoptosis. miRNAs→ micro RNAs that negatively regulate gene expression. p53→ tumor suppressor protein.
