Cancer is a substantial world health threat, & a largest cause of death in peoples of various age groups and economic backgrounds. This dramatic increase in the global burden of cancer has spurred research and many pharmacological studies as an attempt to limit the progression of this disease. Painful, expensive chemotherapy by dietary supplements have come forth as a novel significant approach in ailment of cancer. Since ancient times mushrooms has been used a good resource of dietary supplement. Mushroom is attributed by many medicinal properties, due to presence of phytochemicals, antioxidant, anticancer, antiviral, antimicrobial, anti-diabetic, anti-inflammatory etc. bioactive compounds in fruiting bodies and cultured mycelium. Polysaccharides and antioxidant have been extensively studied biologically active compounds of mushroom for their cytotoxic as well as immunomodulation properties. In this review we will highlight the recent findings on anticancereous bioactive compounds of mushroom, their therapeutic potentials and mode of action and the need for further investigation in cancer...

Since ancient times, herbal drugs are used in traditional system of medicine such as Siddha, Ayurvedaand Unani. The allopathic system of medicine adopted many medicinal plants to derive newer molecules for challenging diseases. The plant Indigofera aspalathoides which is well known as ‘Sivanar vembu’ is widely used for skin diseases. Phytochemical and Pharmacological researchers have screened it for its anti-cancerous and antioxidant property. This review focuses all updated information about its authentication, phytochemistry and pharmacology. The phytochemical evaluation of the plant showed phenolic compounds, tannin, alkaloides, triterpenes, flavones, saponin and steroids. This drug is widely screened for its anti-cancerous and anti-oxidant activity. Anti-microbial, hypoglycemic, hepatoprotective, anti-inflammatory and antiviral activity were also reported. A thailam (oil prepared by traditional extraction procedure) prepared from this plant is widely used by the Siddha practioners for various ailments. This review focuses the lot of medicinal properties of the plant through the scientific validation and strongly supports the traditional...

Here, we review the development of prospective image processing systems in molecular diagnostics and of pharmacologically active ingredients for patient-specific therapeutic approaches. These projects require not only high demands on quality, safety, and specificity but also, rapid, efficient and irreversible ligation routes during the synthesis of future pharmaceuticals. The Diels-Alder ligation reaction with inverse electron demand (DARinv) is an eligible technology not restricted to medical applications, but valuable in selective modification by functionalization of polymers, organic and inorganic surfaces and micro arrays. Additionally, the DARinv technology is considered as an attractive strategy-platform for efficient syntheses of promising pharmacologically active components and derivatives of natural molecules with an optimized therapeutic index. We like to encourage scientists working with the brilliant concept of Sharpless’s “Click chemistry”, to intensify their research with this valuable DARinv technology able to open the door for regioselective, stereospecific, and bioorthogonal exigent syntheses of substances of highest quality inconceivable so...

Cancer is a group of disease characterized by unregulated cell growth and spread of cells from site of origin to other sites in body. Two main genetic changes lead to cancer they are inactivation of tumour suppressor gene and activation of proto-oncogene. Ras gene is a proto-oncogene, when this gene activated it stimulates signalling pathway and that causes unregulated proliferation of cells. Ras family is a group of three precursors H-Ras, K-Ras and N-Ras. It was analyzed that more than 30% of cancers occurs due to Ras gene. But most of the Ras related cancers are occur due to mutations in H-Ras gene. In H-Ras gene codons 12, 13 and 61 are hotspots. Bioinformatics tools are help to find out the amino acid sequence from which got the gene sequence of H-Ras. Using the H-Ras gene sequence, six primer pairs were designed to amplify the DNA of patients with the potential mutations. Designed primers can be used for the diagnosis of H-Ras related...

FDTs are designed to disintegrate rapidly on contact with saliva and enables oral administration without water or chewing, these formulations offer increased convenience and ease of administration with the potential to improve patient compliance, particularly in certain populations, where swallowing of conventional solid oral dosage forms presents difficulties. In the present study, the effect of a natural superdisintegrant Fenugreek and synthetic superdisintegrants sodium starch glycolate (SSG) was compared in the formulations of fast dissolving tablets (FDT). FDTs of Diclofenac (model drug) were prepared by direct compression method. These tablets were evaluated for weight variation, hardness, thickness, disintegration time, water absorption ratio, friability and dissolution. Swelling index was also investigated with an aim to compare the swelling property of Fenugreek with Sodium starch glycolate (SSG). Fenugreek showed higher swelling index than SSG. Hence, the present study revealed that this natural superdisintegrants showed better disintegrating property than the most widely used synthetic superdisintegrants like...
