Chalcones constitute a group of phenolic compounds that command an increasing interest on cancer research. Natural chalcones are widespread through the plant kingdom. The most abundant and investigated chalcones are isoliquiritigenin, flavokawain and xanthohumol, which are present in the Fabaceae, Piperaceae, Cannabaceae, and Moraceae families. These chalcones have been shown to be promising lead antitumor-ch Read More

O-Prenyl secondary metabolites (3,3-dimethylallyl, geranyl-, farnesyl- and related biosynthetic derivatives) represent a class of rarely occurring natural products. In the last two decades such compounds have been found to exert promising and effective pharmacological activities, mainly in terms of anti-cancer properties. To date about 350 oxyprenylated secondary metabolites, the most part of which having a phenylpropan Read More

Flavonoids are secondary metabolites abundantly present in commonly consumed fruits and vegetables. They possess diverse properties such as anti-inflammatory, anti-oxidant and anti-cancer. Epidemiologic studies suggest that an enrich flavonoids diet is linked to a decreased risk of breast cancer. These protective properties are due to the alteration of numerous signalling pathways involved in cancer-related phenomena su Read More

Cancer development is mostly due to a deregulation of cell death as cancer cells become resistant to apoptosis by increasing expression of anti-apoptotic proteins belonging to the Bcl-2 family. Mcl-1 is one anti-apoptotic protein, which is mainly responsible for cancer cell resistance as it is overexpressed by most cancer cell types. Many research projects aim to restore cancer cell death by using natural pharmacological sca Read More

During past two decades, plant-derived bioactive compounds have been reported as novel therapeutic agents for prevention and/or mitigation of different human diseases such as cancer, inflammation, cardiovascular and neurodegenerative diseases. Hesperidin is known as one of the most common and bioactive constituents of Citrus (C) species which possesses multiple health-promotion effects. A plethora of scientific litera Read More

Phytocannabinoids (pCBs) are lipid-soluble phytochemicals present in the plant, Cannabis sativa L. and non-cannabis plants which have a long history in recreation and traditional medicine. The plant and the constituents isolated were central in the discovery of the endocannabinoid system (ECS), the most new target for drug discovery. The ECS includes two G-protein-coupled receptors; the cannabinoid receptors-1 and -2 (C Read More

Terpenes have received a great deal of attention in the scientific literature due to complex, synthetically challenging structures and diverse biological activities associated with this class of natural products. Based on the number of C5 isoprene units they are generated from, terpenes are classified as hemi- (C5), mono- (C10), sesqui- (C15), di- (C20), sester- (C25), tri (C30), and tetraterpenes (C40). Among these, sesterterp Read More

Mangrove associated endophytes are treasure chests for bioprospecting especially in light of the need for new anticancer leads that are necessary to overcome drug resistance of cancer cells. This review highlights the potent anti-tumour compound phomoxanthone A (PXA), which represents a tetrahydroxanthone atropisomer derived from the mangrove-associated fungus Phomopsis longicolla. PXA displayed strong anti-tumour Read More

Cholesterol-5,6-epoxide hydrolase (ChEH) in mammals is a heterooligomeric complex of two cholesterogenic enzymes that control mammalian developmental programs. Following the identification of this complex, it was hypothesized that a new metabolic pathway existed that centered on 5,6-epoxy cholesterols (5,6-EC). Conjugation products of 5,6-EC with biogenic amines known to interact with ChEH subunits were synthes Read More
