The invention is based on the discovery that STM/Hop promotes proliferation of human glioblastoma-derived cells but not of normal astrocytes and that the proliferation requires the binding of STM/Hop to PrP^C. The invention is directed to methods for treating cancer which rely on interfering with the Hop-PrP^C interaction and to peptides, and antibodies raised against the peptides, which directly provide that interference. The invention is further based on the discovery that STI1_230-245 peptide and its human homologue Hop23o-245 provide the desired interference with the STI1/Hop-Pre interaction and inhibit the STI 1/Hop-induced proliferation of glioma and glioblastoma cells. The invention is thus further directed to methods of treating cancer that employ these peptides and functional derivatives thereof, and antibodies directed to the peptides and derivatives. The invention is further directed to means of treating cancer which involve reducing the effective amount of Hop or reducing the expression of Hop. The invention is further directed to means of alleviating or eliminating the side effects of drug therapy and radiotherapy used in treating patients with brain cancers.

The novel positively charged prodrugs of acetylsalicylic acid and its analogues in the general formula(1) 'Structure 1' were designed and synthesized. The compounds of the general formula(1) 'Structure 1' indicated above can be prepared from functional derivatives of ASA or its analogues,(for example acid halides or mixed anhydrides), by reaction with suitable alcohols, thiols, or amines. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs, but also bonds to the negative charge on the phosphate head group of membranes and push the pro-drug into the cytosol. The experiment results suggest that the pro-drug, diethylaminoethyl acetylsalicylate.AcOH, diffuses through human skin -400 times faster than acetylsalicylic acid itself and -100 times faster than ethyl acetylsalicylate. In plasma, 80% of these pro-drugs can change back to the drug in a few minutes. The pro-drugs can be used medicinally in treating any aspirin-treatable conditions in humans or animals and be administered not only orally, but also transdermally for any kind of medical treatments and avoid most of the side effects of aspirin, most notably GI disturbances such as dyspepsia, gastroduodenal bleeding, gastric ulcerations, and gastritis. Controlled transdermal administration systems of the prodrug enable the aspirin in the blood to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of aspirin.

The present invention belongs to the field of polymer compound material.

The O-quaternary-N-thiourea chitosan provided in the invention achieves a substantial increase in antibacterial property compared with chitosan. The invention can be used in a plurality of application fields of antibacterial material, daily chemical products, industrial wastewater treatment and the like.
