Background: Colon cancer is one of the most common malignancies in many regions of the world and is thought to arise from the accumulation of mutations in a single epithelial cell of the colon and rectum. The benzimidazole comprises a important pharmacophore and privileged structure in modern drug discovery. Various substituted benzimidazole derivatives have been found to possess potential anticancer properties. Objective: The study aimed to prove the anti-colon cancer activity of novel benzimidazole derivative 4-(1H-benzo[d]imidazol-2-yl)-6-phenylpyrimidin-2-amine loaded chitosan nanoparticle (BZI 3 nano) by an 1, 2 Dimethylhydrazine (DMH) Induced rat model in-vivo study and identify the targeting efficiency of BZI 3 nano to treat colorectal cancer. Method: The effect of novel benzimidazole derivative 4-(1H-benzo[d]imidazol-2-yl)-6-phenylpyrimidin-2-amine loaded chitosan nanoparticle (BZI 3 nano) on the formation of aberrant crypt foci (ACF), apoptosis, histopathology, body weight, organs weight and heamotological parameters were studied in 1,2-dimethylhydrazine (DMH)-induced colon cancer in rats. Results: BZI 3 nano (5 mg/kg, p.o) administration significantly reduced ACF number and increased the weight gain and apoptotic index compared to DMH treated group. The histological alterations induced by DMH were also significantly improved. Conclusion: In-vivo anticancer activities results revealed that the presence substituted benzimidazole derivative nanoparticle (BZI 3 nano) could have the anticancer potential of the scaffold and selective, good target for drug discovery, which can be regarded as promising anticancer potential.

India is known for its traditional medicinal system – Ayurveda, Siddha and Unani. There are several references in our ancient literature about the miraculous curing properties of the plant-based drugs. “Rig Veda and Atharva veda” seems to be the earliest record of use of plant in the medicine. A stomach ulcer involves an erosion in a person’s gastrointestinal tract. ‘Peptic’ is derived from Greek word “Peptikos” who’s meaning is related to digestion. Peptic ulcer occurs in the part of the gastrointestinal track which is exposed to gastric acid and pepsin (i.e) the stomach and duodenum. The extract of Tephrosia purpurea flowers against viruses and is very good antibacterial against Gram +ve and Gram -ve strain. The Plant extract was prepared and the phytochemical analysis was performed. The extract was administered with animals. The drug were administered orally once daily for 2 days and 45 min prior to pyloric ligation. The animals are sacrificed after four hours of pylorus ligation. The result indicates that, Flavonoids and Tannins have shown to be present in the TPAL treated groups. Since flavanoids antagonize aggressive factor which play a decisive role in the pathogenesis of gastric lesion and also enhance defence factor to protect the gastric mucosa from injury. Flavanoids diminish histamine secretion from mast cell by inhibition of histidine decarboxylase and stimulate PG biosynthesis. So the antiulcer activity of TPAL may be attributed to its flavonoid content. The study concluded that TPAL has an anti ulcer activity which may be due to protection and the strengthening of the mucosal defensive factor like mucus, bicarbonate, prostaglandin.
