AD is the most common form of dementia. Extracellular senile (amyloid) plaques and intracellular neurofibrillary tangles (NFTs) are hallmarks of the disease. Vigna radiata and Vigna pilosa are plants used in many Ayurvedic formulations used in the management of dementia and related conditions. The present study was aimed to evaluate the neuroprotective effect of these plants on an amyloid-β (Aβ) 1-42 model of Alzheimer{\textquoteright}s disease in rats. Duration of the study was 21 days. After the recovery period post Aβ1-42 ICV administration, from the 8thday, the ethyl acetate extract of Vigna radiata and ethanolic extract of Vigna pilosa (200mg/kg, 400mg/kg), Donepezil (3mg/kg) treatments were made once daily p.o till the 21st day. Cognitive behavioural studies were conducted using radial maze test, Step-through Passive Avoidance Test. The animals were further subjected to euthanasia and the brain were collected and evaluated for antioxidant parameters and brain cytokine levels. The brain tissues were subjected to histopathological examination. The treatment with the extracts significantly improved the cognitive capability of the rats in the Radial arm maze task and step through passive avoidance test. It also reduced oxidative stress, which was evident by the lower levels of lipid peroxide and nitric oxide as well as elevated levels of antioxidant enzymes like catalase, superoxide dismutase and reduced glutathione. The treatment alleviated neuroinflammation in rats by decreasing the concentration of neuroinflammatory markers in a dose-dependent manner. From the results it can be concluded that the plants Vigna radiata and Vigna pilosa has beneficial effects in the improvement of cognitive impairment AD, by reducing oxidative stress and neuroinflammation.

Cancer is one of the dreadful illnesses that cause mortality in many individuals around the world. Present cancer treatments generally include surgery, radiation therapy with chemotherapy. One of the primary sources of anticancer drugs are natural products that exhibit impressive potential in medicines. Plant and microbial secondary metabolites are an important source for cancer drug development. The ocean has an immense collection of flora and fauna overflowing with natural compounds having potent pharmaceutical significance. Marine bioprospecting has just started recently hence, marine ecosystem has not yet been explored properly. Nearly 68 percent of the drugs derived from marine sources are utilized for cancer and the remaining are utilized for inflammation, pain relief etc. Ongoing advancement in synthetic processes has helped in solving the limitations caused due to the complicated structure of natural products. Unlimited potent sources of compounds that can be isolated having diverse structures are found in the marine biodiversity. Only 1\% of the marine microorganisms have been distinguished till now. Coral reefs and mangrove ecosystem have been focused for bioprospecting on the grounds that they have an elevated level of biodiversity. This review focuses on pharmacologically active anti-cancer lead discovery from marine ecosystem. The review has also tried to describe the structure

Hygrophila auriculata, belonging to the family Acanthaceae, is a promising medicinal plant with great economic potential. The medicinal value of H. auriculata has been appreciated in the ancient medical literature. The plant contains terpenoids, alkaloids, flavonoids, and is traditionally known as an aphrodisiac, renal tonic, and for its health-promoting properties. The plant is cultivated throughout India. However, systematic information on the different aspects of this species is not available. In this review, an attempt has been made to present this information.
