The objectives of the present investigation were to prepare the 5-Fluorouracil (5-FU) loaded chitosan microspheres for colon targeting and its in vitro cytotoxicity analysis on HT-29 human colon cancer cell lines. Chitosan microspheres prepared by the emulsion polymerization method were analyzed for morphology, mean particle size, drug polymer interaction, entrapment efficiency, in vitro drug r...

Several lines of evidence suggest that nonsteroidal antiinflammatory drugs may be effective in preventing colorectal cancer. These include animal experiments, case-control studies, and clinical experience with sulindac in promoting the regression of adenomatous colon polyps in adenomatous polyposis coli. We determined the antiproliferative activity of various nonsteroidal antiinflammatory drugs...

Proline-, glutamic acid-, and leucine-rich protein 1 (PELP1), a coregulator of estrogen receptors alpha and beta, is a potential protooncogene implicated in several human cancers, including sexual hormone-responsive or sexual hormone-nonresponsive cancers. However, the functions of PELP1 in colorectal cancer remain unclear. In this study, western blot and bioinformatics revealed that PELP1 expr...

The novel nitric oxide-donating nonsteroidal antiinflammatory drugs (NO-NSAIDs), consisting of a traditional NSAID to which a NO releasing moiety is covalently attached, may have an important role in colon cancer prevention and/or treatment. Preclinical studies have shown that NO-aspirin (NO-ASA) is more potent than traditional ASA in preventing colon cancer. Preclinical and clinical studies ha...

Disrupted apoptosis not only confers a survival advantage to cancer cells but also causes resistance to chemotherapies. Therefore, inducing cell apoptosis has become a promising strategy for anticancer treatment. Patrinia scabiosaefolia (PS) has long been used to clinically treat various types of malignancies including colorectal cancer (CRC). However, the precise mechanism of its tumoricidal a...

Bis(3'-indolyl)methane (DIM) is a metabolite of the phytochemical indole-3-carbinol, and both compounds exhibit a broad spectrum of anticancer activities. We have developed a series of synthetic symmetrical ring-substituted DIM analogues, including 5,5'-dibromoDIM, which are more potent than DIM as inhibitors of cancer cell and tumor growth. In colon cancer cells, 5,5'-dibromoDIM decreased cell...

 Caffeic acid phenethyl ester(CAPE) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. A group of heterocyclic esters of caffeic acid was synthesized using Mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catecho...
