“…This is an obvious area for future research if these active constituents are to be produced on a commercial scale. There are reports dating back more than 50 years of natural products chemistry with detailed descriptions of the identification and synthesis of complex organic compounds, particularly flavone-like molecules [3,4,14,17,39,55,60,67,80,82]. Importantly, some of the studies have also described the biomedical efficacy of these compounds.…”

Pongamia pinnata (L.) Pierre is a fast-growing leguminous tree with the potential for high oil seed production and the added benefit of the ability to grow on marginal land. These properties support the suitability of this plant for large-scale vegetable oil production required by a sustainable biodiesel industry. The future success of P. pinnata as a sustainable source of feedstock for the biofuels industry is dependent on an extensive knowledge of the genetics, physiology and propagation of this legume. In particular, research should be targeted to maximizing plant growth as it relates to oil biosynthesis. This review assesses and integrates the biological, chemical and genetic attributes of the plant, providing the basis for future research into Pongamia's role in an emerging industry.

“…Mangroves are well adapted to cope with biotic stress factors caused by herbivores or plant pathogens through accumulation of numerous biologically active natural products that include polyphenols, limonoids and polyketide derivatives with many of them exhibiting pronounced biological activities (e.g. Yang et al 2006;Li et al 2006;Bao et al 2007;Cui et al 2007). On the other hand, Mangroves are also hosts to numerous endophytic fungi that are likewise interesting sources of bioactive secondary metabolites.…”

This review highlights recent findings of our group on bioactive marine natural products isolated from marine sponges and marine derived fungi. The activated chemical defence of the Mediterranean sponge Aplysina aerophoba is introduced as an example of a dynamic response of marine sponges to wounding. Following tissue disrupture preformed brominated isoxazoline alkaloids are enzymatically cleaved and thereby give rise to aeroplysinin-1 which is believed to protect sponges from invasion of pathogenic bacteria. A preliminary characterization of the membrane bound enzyme(s) involved in the cleavage reaction is presented. Bromotyrosine derived, oxime group bearing peptides, the so called bastadins, obtained from the sponge Ianthella basta and some of their synthetic derivatives were shown to exhibit pronounced antifouling activity against larvae of the barnacle Balanus improvisus. The antifouling activity could be traced to the oxime group as an important pharmacophore that was also found to be present in other sponge derived natural products exhibiting antifouling activity. Marine derived fungi that reside within invertebrates such as sponges or inside Mangrove plants are emerging as a new source of bioactive metabolites as demonstrated for Aspergillus ustus and Alternaria sp. that were isolated from the sponge Suberites domuncula or from the Mangrove plant Sonneratia alba, respectively. The former fungus yielded new moderately cytotoxic sesquiterpenoids of the drimane type whereas the latter was found to produce polyketides such as alternariol that exhibited strong and selective inhibitory activity against several protein kinases, for instance Aurora A and B which are targets for anticancer chemotherapy.

Advances in Plant Biopesticides

Insect pests are considered the major hurdle in enhancing the production and productivity of any farming system. The use of conventional synthetic pesticides has led to the emergence of pesticide-resistant insects, environmental pollution, and negative effects on natural enemies, which have caused an ecological imbalance of the predator-prey ratio and human health hazards; therefore, eco-friendly alternative strategies are required. The plant kingdom, a rich repertoire of secondary metabolites, can be tapped as an alternative for insect pest management strategies. A number of plants have been documented to have insecticidal properties against various orders of insects in vitro by acting as antifeedants, repellents, sterilant and oviposition deterrents, etc. However, only a few plant compounds are applicable at the fi eld level or presently commercialised. Here, we have provided an overview of the broad-spectrum insecticidal activity of plant compounds from neem, Annona , Pongamia , and Jatropha . Additionally, the impact of medicinal plants, herbs, spices, and essential oils has been reviewed briefl y.
