Recent progress in the study of anticancer drugs originating from plants and traditional medicines in China is reviewed in this paper, with particular emphasis on taxol, daidzein, acetyl boswellic acid,curcumin and ginsenosid Rh2.展开更多

Meanwhile, molecular targeted drug therapy for esophageal cancer are attracting more and more attention from doctors and experts. However, little study has been done towards the effect of this approach for treating esophageal squamous cell carcinoma. This paper, therefore, intends to explore the possibilities of applying EGFR-TKI inhibitors or anti-EGFR monoclonal antibody in esophageal squamous cell carcinoma by studying the mutations of EGFR, K-ras and B-raf in the esophageal squamous cell carcinoma tissues. Methods: Thirty-five cases of resected specimens of diagnosed esophageal squamous cell carcinoma with complete clinical and pathological data from January to April 2009 were collected. Pyrophosphate was used for observing the mutations of EGFR, K-ras and B-raf in the esophageal squamous cell carcinoma tissues. Results: Examinations were undertaken respectively to the codon segment 746-754 of exon 19 in EGFR genes, codon 12 and 13 in K-ras genes as well as condon 600 in B-raf genes. No mutation was found in EGFR and B-raf genes with mutation rate 0% (0/35), all of codon 12 in K-ras genes were wild-type without any mutation, while 2 specimens of codon 13 had mutations with mutation rate of 5.71% (2/35). Conclusion: In treating esophageal squamous cell carcinoma patients, all K-ras genes are expressed as wild type due to low mutation rate; cetuximab is effective due to low mutation rate of B-raf while EGFR-TKI inhibitor will not be effective enough because of low mutation rate of EGFR genes.展开更多

However, poor selectivity, high toxicity and intrinsic or acquired drug resistance profoundly limit their application, which encourages the development of novel transition metal-based anticancer agents with different mechanisms of action. To this end, transition metal complexes that can simultaneously act on more than one target, termed as single-molecule multi-targeting complexes, have attracted increasing attention because of their enhanced efficacy and diminished chance of drug resistance. In this review, we systematically discuss the recent progress in the development of platinum- and ruthenium-based anticancer agents, in particular the rational design of platinum and ruthenium complexes with multi-targeting features.展开更多
