A review on edible vaccines and their prospects.

Abstract: For a long time, vaccines have been the main mode of defense and protection against several bacterial, viral, and parasitic diseases. However, the process of production and purification makes them expensive and unaffordable to many developing nations. An edible vaccine is when the antigen is expressed in the edible part of the plant. This reduces the cost of production of the vaccine because of ease of culturing. In this article, various types of edible vaccines that include algal and probiotics in addition to plants are discussed. Various diseases against which research has been carried out are also reviewed. This article focused on the conception of edible vaccines highlighting the various ways by which vaccines can be delivered.

Improving Bioavailability of Vitamin A in Food by Encapsulation: An Update

Abstract: Vitamin A is an obligatory micronutrient for healthy human life as it cannot be synthesized de novo and has to be acquired from dietary sources. The poor water solubility and susceptibility against photochemical degradation make vitamin A relatively unstable during food processing as well as storage. To combat prevailing vitamin A deficiency, various strategies have already been adopted in pharmaceutical industries to develop vitamin A formulation which has the ability to protect and minimize its degradation. On the one hand, in pharmaceutical formulations, vitamin A may be coupled with sub-toxic effects due to its buildup in the liver and other vital organ, while on the other hand its involvement against various health disorders such as neurodegenerative diseases, cardiovascular diseases and cancer has recently compelled the population to achieve vitamin A via pharmaceutical supplements, functional foods or food supplements. The success of pharmaceutical application encouraged food technologists to develop numerous premixes encapsulating vitamin A appropriately which can be successfully applied for the development of food supplements or vitamin A-rich functional foods. So this chapter is an update of the principal encapsulation techniques adopted for the development of vitamin A nanomaterials to improve its bioavailability and associated challenges with fabrication method.

Novel phenyl and thiophene dispiro indenoquinoxaline pyrrolidine quinolones induced apoptosis via G1/S and G2/M phase cell cycle arrest in MCF-7 cells

Abstract: New phenyl and thiophene dispiro indeno quinoxaline pyrrolidine quinolone analogues were synthesized by a one-pot four-component [3+2] cycloaddition reaction between (E)-3-arylidene-2,3-dihydro-8-nitro-4-quinolones, o-phenylenediamine, ninhydrin, and benzylamine/thiophenemethylamine. The structure and regio- and stereochemistry of the compounds have been confirmed by various spectroscopic and X-ray diffraction analyses. The observed regio- and stereoselectivity of the compounds were further enlightened by DFT calculations. Further, the in vitro cytotoxic effects of the compounds were evaluated by MTT assay. The compounds exhibited significant inhibition activity towards the tested cancer cells HeLa and MCF-7. Among the synthesized compounds compound 9e showed the highest inhibitory potency against MCF-7 cells. Mechanistic cell death studies revealed that cell death was induced by 9e against MCF-7 cells by ROS mediated G1/S and G2/M phase cell cycle arrest apoptosis. The apoptotic cell death was quantified by the annexin V-FITC/PI staining method. The binding mode of compound 9e was further examined by in silico molecular docking studies.
