Treatment of lung carcinoma remains a great clinical challenge, and one candidate of interest is a novel type of compounds called cyclotides (MCo-52-2-based cyclotides). We plan to test cyclotides on several human lung carcinoma cell lines with different p53 phenotypes (null, mutated, and wild type), testing its efficacy on animal models of lung carcinoma; and to continue the development of this cyclotide selecting compounds based on cyclotide MCo-52-2 with improved activity. This will be accomplished by using the power of molecular evolution using cyclotide MCo-52-2 as template. Cyclotides with potent in vitro Hdm2/HdmX inhibitory properties will be further tested in vivo using several mouse models of lung carcinoma. We anticipate that this novel type of cyclotide-based inhibitor will have a broad spectrum of antitumor activity in human lung carcinoma cell lines both in vitro and in vivo. This could lead to the next generation of therapy of this type of cancer.
