摘要:
Deuterated rapamycin can be controllably introduced target locations within the patient's body by using an implantable medical device having a structure incorporated with a therapeutic agent comprising a deuterated rapamycin. Representative deuterated rapamycins include epi-7-deuteromthyl rapamycin, 7,43-d6 rapamycin, 7-deuteromethyl rapamycin and 31,42-d2-rapamycin and isomers thereof, and mixtures thereof. The deuterated rapamycin can also be glycosylated.
摘要:
Cyclosporine derivatives are disclosed which possess enhanced efficacy and reduced toxicity over naturally occurring and other presently known cyclosporins and cyclosporine derivatives. The cyclosporine derivatives of the present invention are produced by chemical and isotopic substitution of the cyclosporine A (CsA) molecule by: (1) Chemical substitution and optionally deuterium substitution of amino acid 1; and (2) deuterium substitution at key sites of metabolism of the cyclosporine A molecule such as amino acids 1, 4, 9. Also disclosed are methods of producing the cyclosporine derivatives and method of producing immunosuppression with reduced toxicity with the disclosed cyclosporine derivatives.

摘要:
The synthesis of deuterated analogues of rapamycin is disclosed together with a method for use for inducing immunosupression and in the treatment of transplantation rejection, graft vs host disease, autoimmune diseases, diseases of inflammation leukemia/lymphoma, solid tumors, fungal infections, hyperproliferative vascular disorders. Also described is a method for the synthesis of water soluble deuteratred rapamycin compounds and their use as described above.

摘要:
A series of activated iodo-benzamide derivatives are described as antineoplastic and antiviral drug compounds. The compounds generally possess a chelating group, a thiol trapping group and an activating group. The presumptive mechanism of action in preventing cancer cell and virus replication is through inhibition of the binding of transcription factors to zinc finger binding domains. The compounds are effective in inhibiting growth of a variety of human and animal tumor and leukemia cell lines at low concentrations.

摘要:
The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy and reduced toxicity over the individual isomers and over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISATX247, and derivatives thereof. Mixtures of ISATX247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISATX247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture may range from about 10 to 90 percent by weight of the (E)-isomer to about 90 to 10 percent by weight of the (Z)-isomer, based on the total weight of the mixture.
