A number of prenylated benzoic acids derivatives with interesting biological activities have been previously isolated and characterized from different species of piperaceae family. Several Piper species contained structurally similar compounds with diverse biological activities such as anti-bacterial, anti-fungal, insecticidal as well as anti-parasitic all of which produces compounds that can be classified as prenylated benzoic acid derivatives. Piper sp has proven to serve as a source of potential anti-infective agents by developing a biosynthetic route to the synthesis of prenylated benzoic acids derivative natural products as their chemical defense system. Despite the frequent isolation of these interesting compounds with strong biological activity, yet none have been taking into consideration for development into therapeutic...

A prebiotic is a living microorganism that, when administered in sufficient numbers is beneficial to the host and exerts health benefits beyond inherent basic nutrition. Prebiotics include foods, medicines and dietary supplements. In general, the benefits of the regular consumption of prebiotics include enhanced immune function, improved colonic integrity, decreased incidence and duration of intestinal infections, down-regulated allergic response, and improved digestion and elimination. Pharmaceutical and nutritional industries are exploring more natural treatments for health conscious consumers as natural treatments have been effective since immemorial and are staging a comeback and natural ‘renaissance’ is happening all over the...

Microbubbles are bubbles smaller than one millimeter in diameter, but larger than one micrometer. Microbubbles designate air or gas filled microspheres suspended in a liquid carrier phase which generally results from the introduction of air or gas. The liquid phase contains surfactants to control the surface properties as well as stability of the bubble. Microbubbles have an average size less than that of RBC’s i.e., they are capable of penetrating even into the smallest blood capillaries & releasing drugs or genes, incorporated on their surface, under the action of ultrasound. Microbubbles in general have a wide variety of applications. However in the biomedical field these are primarily used as diagnostic agents in combination with ultrasound for molecular imaging of various organs and even tumours. These are also proposed for drug and gene delivery to targeted regions in combination with various ligands. Most of the physicians today prefer imaging with ultrasound in combination with microbubbles compared to other diagnostic techniques for low cost and rapidity. They are used in medical...

Medicines obtained from plant source are known as an herbal medicine, and the herbal medicine are one which make human healthy without causing any of harmful effect. Madhuca Indica is a plant of Indian origin having tremendous therapeutic potential but is not fully utilized. It is hidden from the eyes of the researchers and other botanist. Madhuca Indica has several pharmacological activity, and potential to provide health to the society. It is used as Anti diabetic, antiulcer, hepato protective, anti pyretic, anti fertility, analgesic, anti oxidant, swelling, inflammation, piles, emetic, dermatological, laxative, tonic, anti burn, anti earth worm, wound healing headache and many more problems. Here is a misconception about mahua tree that it is used as liquor and harmful for health, but this is what after the fermentation process, so the present review deals with the general and chemical profile of Madhuca Indica and its economic importance including medicinal and other uses, and tried to emphasize the most potent...

In general, we know that small intestine is mostly the site for drug absorption but in some cases the drug needs to be targeted to some other sites for absorption due to various factors like any disease condition, degradation related situations, for sustained release of drugs etc. Colon targeted drug delivery is a relatively new concept for the absorption of drugs as it offers near neutral pH. Also it offers long residence time, thereby increasing the drug absorption. The nature of food and enzymes does not affect the drug absorption. Colon has proved to be a site for the absorption of poorly soluble drugs. For the successful targeting of drugs to colon the dosage form should be designed such that it prevents the drug release in upper GIT and releasing it in the colonic region. This review article comprises of the various aspects of colon targeting which we should know before experimenting the technique and their IVIVC using recent evaluation models through x-ray imaging and...
