Abstract
A method of treating cancer through use of guanosine 3′,5′-cyclic monophosphate (cyclic GMP). Cyclic GMP decreases the number of human breast cancer and prostate adenocarcinoma as well as small-cell and squamous lung cells in culture by 30% (1 μM), 84% (1 mM), 31% (1 μM), and 30% (1 μM), respectively. Cyclic GMP decreases DNA synthesis in human pancreatic, breast, and prostate adenocarcinomas as well as small-cell and squamous cell carcinomas of the lung at its 1 μM concentration by 51%, 54%, 56%, 50% and 52%, respectively. Cyclic GMP when infused for one week decreases the tumor volume of human pancreatic adenocarcinomas in athymic mice 95% compared to untreated animals with human pancreatic adenocarcinomas.
Claims18
A method of inhibiting the growth of cancer cells in vivo comprising the step of contacting at least one target cancer cell in vivo with an effective amount of 8-bromo-cyclic guanosine monophosphate, or a composition comprising 8-bromo-cyclic-guanosine monophosphate, and further comprising contacting the at least one target cancer cell in vivo with an effective amount of a peptide hormone selected from the group consisting of long acting natriuretic peptide, vessel dilator peptide, and kaliuretic peptide, whereby the in vivo growth of the at least one target cancer cell is inhibited, wherein the target cancer cell is selected from the group consisting of human pancreatic adenocarcinoma, human small-cell carcinoma, and human squamous cell carcinoma.
A method of inhibiting the growth of cancer cells in vivo comprising the step of contacting at least one target cancer cell in vivo with an effective amount of 8-bromo-cyclic guanosine monophosphate, or a composition comprising 8-bromo-cyclic-guanosine monophosphate, and further comprising contacting the at least one target cancer cell in vivo with an effective amount of a peptide hormone selected from the group consisting of long acting natriuretic peptide, vessel dilator peptide, and kaliuretic peptide, whereby the in vivo growth of the at least one target cancer cell is inhibited, wherein the target cancer cell is selected from the group consisting of human pancreatic adenocarcinoma, human small-cell carcinoma, and human squamous cell carcinoma, and wherein the contacting step does not comprise contacting the at least one target cancer cell with atrial natriuretic peptide (ANP).
