Definitions
- the present invention relates to a method for treating and/or preventing hepatitis delta virus (also referred to as hepatitis D) by blocking the prenylation of CXXX box containing proteins by administering a therapeutic amount of a protein-prenyl transferase inhibitor.
- hepatitis delta virus also referred to as hepatitis D
- HDV hepatitis delta virus
- the last four amino acids of large delta antigen are Cys-Arg-Pro-Gln-COOH.
- This COOH-terminal configuration is termed a CXXX box, where C is cysteine and X is any amino acid.
- the CXXX box has been implicated as a substrate for prenyltransferases that add to the cysteine 15 (farnesyl) or 20 (geranylgeranyl) carbon moieties derived from mevalonic acid.
- cysteine 15 farnesyl
- 20 geranylgeranyl carbon moieties derived from mevalonic acid.
- Glenn et al determined that large delta antigen undergoes prenylation in cultured cells and thus is a substrate for prenylation which is required for productive viral infection. In fact, Glenn et al found that mutation of Cys 211 (the only cysteine in large delta antigen) in the CXXX box of the large delta antigen abolished both prenylation and viral particle formation. In conclusion, Glenn et al suggest "prenylation as a new target for anti-HDV therapy.” As strategies designed to interfere with the prenylation stage of the HDV life cycle, Glenn et al suggest "drugs that inhibit enzymes along the prenylation pathway, and CXXX box analogs.” (See page 1332).
- Squalene synthetase is a microsomal enzyme which catalyzes the reductive dimerization of two molecules of farnesyl pyrophosphate (FPP) in the presence of nicotinamide adenine dinucleotide phosphate (reduced form) (NADPH) to form squalene (Poulter, C. D.; Rilling, H. C., in "Biosynthesis of Isoprenoid Compounds," Vol. I, Chapter 8, pp. 413-441, J. Wiley and Sons, 1981, and references therein). This enzyme is the first committed step of the de novo cholesterol biosynthetic pathway.
- FPP farnesyl pyrophosphate
- NADPH nicotinamide adenine dinucleotide phosphate
- Squalene synthetase inhibitors which block the action of squalene synthetase (after the formation of farnesyl pyrophosphate) are disclosed in U.S. Pat. Nos. 4,871,721 and 5,025,003, U.S. application Ser. No. 501,204, filed Mar. 29, 1990, and U.S. application Ser. No. 699,429, filed May 13, 1991.
- post-translational modification of CXXX box containing proteins may be inhibited by administering a protein-prenyl transferase inhibitor which inhibits the transfer of the prenyl group (such as farnesyl, geranyl or geranylgeranyl) to the cysteine of the CXXX box by the protein-prenyl transferase enzyme.
- a protein-prenyl transferase inhibitor which inhibits the transfer of the prenyl group (such as farnesyl, geranyl or geranylgeranyl) to the cysteine of the CXXX box by the protein-prenyl transferase enzyme.
- the protein-prenyl transferase inhibitor will block the protein-prenyl transferase enzyme from catalyzing the transfer of the prenyl group (for example, farnesyl, geranyl or geranylgeranyl) from the prenyl pyrophosphate to the cys residue of the CXXX box. Prenylation being prevented, productive HDV viral infection (hepatitis delta virus) is inhibited.
- prenyl group for example, farnesyl, geranyl or geranylgeranyl
- the present invention resides in a method for blocking or preventing the prenylation of CXXX box containing proteins such as large delta antigen, and thereby inhibit disease promoting effects of the CXXX box containing protein or more specifically prevent and/or treat hepatitis D viral infection, by administering to a patient in need of treatment a therapeutic amount of a protein-prenyl transferase inhibitor.
- the protein-prenyl transferase inhibitors unlike HMG CoA reductase inhibitors, will interfere with prenylation of the large delta antigen and inhibit their transforming activity, yet may or may not interfere with the synthesis of FPP, a precursor in the synthesis of ubiquinones, dolichols and Haem A.
- the activity of the protein-prenyl transferase inhibitors in blocking the protein-prenyl (e.g. farnesyl, geranyl or geranylgeranyl) transferase from catalyzing the transfer of the prenyl group (e.g. farnesyl, geranyl or geranylgeranyl) from the prenyl pyrophosphate to the cys residue of the CXXX box may be assayed by a procedure similar to that described in U.S. application Ser. No. 520,570 filed May 8, 1990, by Barbacid et al, the disclosure of which is incorporated herein by reference.
- Protein-prenyl transferase inhibitors suitable for use herein include compounds disclosed in U.S. application Serial No. 699,429 filed May 13, 1991, by Biller et al. These protein-prenyl transferase inhibitors have the following structure ##STR1## wherein

Abstract
A method is provided for blocking or preventing the prenylation of CXXX box containing proteins thereby preventing and/or treating hepatitis D which includes the step of administering a therapeutically effective amount of a protein-prenyl transferase inhibitor.
Description
The present invention relates to a method for treating and/or preventing hepatitis delta virus (also referred to as hepatitis D) by blocking the prenylation of CXXX box containing proteins by administering a therapeutic amount of a protein-prenyl transferase inhibitor.
J. Glenn et al, "Identification of a Prenylation Site in Delta Virus Large Antigen", Science, Vol. 256, 29 May 1992, pp. 1331-1333, discloses that during replication, hepatitis delta virus (HDV) switches from production of small to large delta antigen which is prenylated and packaged into virus particles.
The last four amino acids of large delta antigen are Cys-Arg-Pro-Gln-COOH. This COOH-terminal configuration is termed a CXXX box, where C is cysteine and X is any amino acid.
The CXXX box has been implicated as a substrate for prenyltransferases that add to the cysteine 15 (farnesyl) or 20 (geranylgeranyl) carbon moieties derived from mevalonic acid. (J. A. Glomset et al, Trends Biochem. Sci. 15, 139 (1990); W. A. Maltese, FASEB J. 4, 3319 (1990); S. L. Moores et al, J. Biol. Chem. 266, 14603 (1991)).
Glenn et al determined that large delta antigen undergoes prenylation in cultured cells and thus is a substrate for prenylation which is required for productive viral infection. In fact, Glenn et al found that mutation of Cys211 (the only cysteine in large delta antigen) in the CXXX box of the large delta antigen abolished both prenylation and viral particle formation. In conclusion, Glenn et al suggest "prenylation as a new target for anti-HDV therapy." As strategies designed to interfere with the prenylation stage of the HDV life cycle, Glenn et al suggest "drugs that inhibit enzymes along the prenylation pathway, and CXXX box analogs." (See page 1332).
Squalene synthetase is a microsomal enzyme which catalyzes the reductive dimerization of two molecules of farnesyl pyrophosphate (FPP) in the presence of nicotinamide adenine dinucleotide phosphate (reduced form) (NADPH) to form squalene (Poulter, C. D.; Rilling, H. C., in "Biosynthesis of Isoprenoid Compounds," Vol. I, Chapter 8, pp. 413-441, J. Wiley and Sons, 1981, and references therein). This enzyme is the first committed step of the de novo cholesterol biosynthetic pathway.
Squalene synthetase inhibitors which block the action of squalene synthetase (after the formation of farnesyl pyrophosphate) are disclosed in U.S. Pat. Nos. 4,871,721 and 5,025,003, U.S. application Ser. No. 501,204, filed Mar. 29, 1990, and U.S. application Ser. No. 699,429, filed May 13, 1991.
In accordance with the present invention, it has been found that post-translational modification of CXXX box containing proteins may be inhibited by administering a protein-prenyl transferase inhibitor which inhibits the transfer of the prenyl group (such as farnesyl, geranyl or geranylgeranyl) to the cysteine of the CXXX box by the protein-prenyl transferase enzyme. The protein-prenyl transferase inhibitor will block the protein-prenyl transferase enzyme from catalyzing the transfer of the prenyl group (for example, farnesyl, geranyl or geranylgeranyl) from the prenyl pyrophosphate to the cys residue of the CXXX box. Prenylation being prevented, productive HDV viral infection (hepatitis delta virus) is inhibited.
Thus, the present invention resides in a method for blocking or preventing the prenylation of CXXX box containing proteins such as large delta antigen, and thereby inhibit disease promoting effects of the CXXX box containing protein or more specifically prevent and/or treat hepatitis D viral infection, by administering to a patient in need of treatment a therapeutic amount of a protein-prenyl transferase inhibitor.
The protein-prenyl transferase inhibitors, unlike HMG CoA reductase inhibitors, will interfere with prenylation of the large delta antigen and inhibit their transforming activity, yet may or may not interfere with the synthesis of FPP, a precursor in the synthesis of ubiquinones, dolichols and Haem A.
The activity of the protein-prenyl transferase inhibitors in blocking the protein-prenyl (e.g. farnesyl, geranyl or geranylgeranyl) transferase from catalyzing the transfer of the prenyl group (e.g. farnesyl, geranyl or geranylgeranyl) from the prenyl pyrophosphate to the cys residue of the CXXX box may be assayed by a procedure similar to that described in U.S. application Ser.
