Nitric oxide donor-type farnesyl thiosalicylic acid derivative, and preparation method and medical application thereof

The invention discloses a nitric oxide (NO) donor-type farnesyl thiosalicylic acid (FTA) derivative, and pharmaceutically acceptable salt, a preparation method and medical application thereof. The FTA derivative is a compound obtained by carrying out heterozygosis on a NO donor furazan nitrogen oxide and Ras protein inhibitor FTA by an ester bond or an amido bond. Pharmacological test results show that the FTA derivative can reserve the Ras protein inhibiting activity of FTA and simultaneously releases high-concertration NO to induce cancer cell apoptosis and enhance the inhibiting action on cancer cell proliferation; compared with the FTA, the FTA derivative has more excellent anti-tumor activity, and therefore, the compound can be suitable for treating various clinical malignant tumours.

Mutated ras peptides for generation of cd8+ cytotoxic t lymphocytes

InactiveUS20100074945A1Enhanced effector functionEnhances CTL activityBiocidePeptide/protein ingredientsCtl epitopeVaccination
Mutant ras oncogene peptides may induce specific anti-ras cellular immune responses in vaccinated patients. Moreover, a human CD8+ CTL epitope(s) reflecting a specific point mutation in the K-ras oncogene at codon 12 was identified. The mutant ras peptide has implications for both active and passive immunotherapies in selected carcinoma patients. A nested 10-mer peptide was identified [i.e., ras5-14(Asp12)], which was shown to bind to HLA-A2 and display specific functional capacity for expansion of the in vivo-primed CD8+ CTL precursors.

Specifically, the pharmaceutical composition contains radix ginseng, radix ophiopogonis and schisandra chinensis fruits. Researches indicate that about 90% of pancreatic cancer, 50% of colon cancer, 30%-40% of lung adenocarcinoma and 5%-40% of leukemia are caused by the ras proto-oncogene overexpression, and a Ras protein becomes a universally accepted target for screening related malignant tumor drugs. Animal experiments indicate that the pharmaceutical composition can specifically down-regulate overexpression caused after ras proto-oncogene mutation, but does not act on wild-type ras proto-oncogenes, so that the pharmaceutical composition is low in toxicity and has no teratogenic effect and no reproduction toxicity; the pharmaceutical composition can be used for preparation of drugs for tumors caused by overexpression after ras proto-oncogene mutation, can be mixed with any one of pharmaceutically acceptable auxiliary materials to prepare various dosage forms, and is expected to be developed into a new-generation antitumor drugs.
