Methods for treatment of cancer by targeting Sirt5
This disclosure demonstrates that inhibition of Sirt5 can suppress malignant transformation of cells. Therefore, methods of treating cancer based on inhibition of Sirt5 are disclosed.
1. A method of treating breast cancer in a subject, comprising administering an effective amount of a Sirt5 inhibitor to said subject, wherein the Sirt5 inhibitor has the following structure:
wherein:
R 1 is a carboxylate alkyl ester;
R 2 is S;
X 0 , X 1 , X 2 , X 3 , X 5 , X 6 and X 7 are each —CH 2 —;
X 4 is —NR 5 —, wherein R 5 is H, methyl, ethyl, isopropyl, phenyl, or benzyl; and
R 3 and R 4 are independently selected from H, hydrocarbon (R), amino acid, dipeptide, tripeptide, oligopeptide, protein, nucleobase, nucleotide, dinucleotide, trinucleotide, oligonucleotide, monosaccharide, disaccharide, oligosaccharide, and protecting groups or a combination thereof or modified form thereof.
2. The method of claim 1 , wherein said Sirt5 inhibitor is prepared to achieve mitochondria-targeted delivery.
3. The method of claim 1 , wherein R 3 and R 4 are independently selected from H, hydrocarbon (R), amino acid, dipeptide, tripeptide, oligopeptide, and protein.
