Application Number:	08/876,705
Patent Claims:	1. A method of treating cancer, susceptible to treatment, in warm blooded mammals comprising administering to said mammal a safe and effective amount of a pharmaceutical composition comprising (1) a safe and effective amount of a chemotherapeutic agent, wherein said chemotherapeutic agent is selected from the group consisting of Taxol, Asparaginase, hydroxyurea, Cisplatin, Cyclophosphamide, Atretamine, Bleomycin, Dactinomycin, Doxorubicin, Etoposide, Teniposide and Plcamydin and (2) a safe and effective amount of N-chlorophenylcarbamate or N-chlorophenylthiocarbamate of the formula: ##STR3## wherein n is from 1 to 3, X is selected from the group consisting of oxygen and sulfur and R is selected from the group consisting of hydrogen, lower alkyl and lower alkenyl, cyclohexyl, phenalkyl of up to 8 carbon atoms, phenyl, and pharmaceutically acceptable organic or inorganic acid salts of these compounds. 2. A method of treating cancer, susceptible to treatment, in warm blooded mammals according to claim 1 comprising administering to said mammal a safe and effective amount of a composition wherein R is alkyl of from 1 to 4 carbons, n is 1, X is O and the chloro is in the 3 position of the phenyl. 3. A method according to claim 2 wherein from about 2 mg/kg body weight to about 800 mg/kg of said N-chlorophenylcarbamate is administered. 4. A method according to claim 3 wherein said pharmaceutical composition is administered orally or enterically, intravenously, parenterally or by injection into or around the tumor site. 5. A method according to claim 4 wherein from about 2 mg/kg body weight to about 400 mg/kg of said N-chlorophenylcarbamates or the N-chlorophenylthiocarbamates is administered and from 0.5 mg/kg body weight to about 400 mg/kg body weight of said chemotherapeutic agent is administered. 6. A method of treating cancer, susceptible to treatment, in warm blooded mammals comprising administering to said mammal a safe and effective amount of a pharmaceutical composition comprising (1) a safe and effective amount of chemotherapeutic agent wherein said chemotherapeutic agent is selected from the group consisting of Taxol, Asparaginase, hydroxyurea, Cisplatin, Cyclophosphamide, Altretamine, Bleomycin, Dactinomycin, Doxorubicin, Etoposide, Teniposide and Plcamydin and (2) a safe and effective amount of N-chlorophenylcarbamate of the formula: ##STR4## wherein n is 1, X is oxygen, and R is selected from the group consisting of alkyl having from 1 to 4 carbons, and pharmaceutically acceptable organic or inorganic acid salts of these compounds, wherein said pharmaceutical composition is administered orally or enterically, intravenously, parenterally or by injection into or around the tumor site. 7. A method according to claim 6 wherein from about 2 mg/kg body weight to about 800 mg/kg of said N-chlorophenylcarbamate is administered. 8. A method according to claim 7 wherein from about 2 mg/kg body weight to about 400 mg/kg of said N-chlorophenylcarbamate is administered and from 0.5 mg/kg body weight to about 400 mg/kg body weight of said chemotherapeutic agent is administered. 9. A method of treating cancer susceptible to treatment in mammals comprising administering to said mammal a safe and effective amount of a pharmaceutical composition comprising a safe and effective amount of 3-(chlorophenyl)carbamic acid 1-methylethyl ester and a safe and effective amount of taxol. 10. A pharmaceutical composition for treating cancers or tumors, susceptible to treatment, comprising (1) a safe and effective amount of a chemotherapeutic agent wherein said chemotherapeutic agent is selected from the group consisting of Taxol, Asparaginase hydroxyurea, Cisplatin, Cyclophosphamide. Altretamine, Bleomycin, Dactinomycin, Doxorubicin, Etoposide, Teniposide and Plcamydin and (2) a safe and effective amount of a N-chlorophenylcarbamate or N-chlorophenylthiocarbamate of the formula: ##STR5## wherein n is 1 to 3; X is selected from the group consisting oxygen and sulfur and wherein R is selected from the group consisting of hydrogen, lower alkyl and lower alkenyl, cyclohexyl, phenyl and phenalkyl of up to 8 carbon atoms and pharmaceutically acceptable inorganic or organic acid salts of these compounds. 11. A pharmaceutical composition according to claim 10 comprising a pharmaceutically acceptable carrier and a safe and effective amount of N-chlorophenylcarbamates or N-chlorophenylthiocarbamates. 12. A pharmaceutical composition according to claim 11 wherein said pharmaceutically acceptable salts are selected from the group consisting of hydrochlorides, acetates, salicylates, nitrates and phosphate salts and mixtures thereof. 13. A pharmaceutical composition for treating cancers or tumors, susceptible to treatment, comprising (1) a safe and effective amount of a chemotherapeutic agent wherein said chemotherapeutic agent is selected from the group consisting of Taxol, Asparaginase, hydroxyurea, Cisplatin, Cyclophosphamide, Altretamine, Bleomycin, Dactinomycin, Doxorubicin, Etoposide, Teniposide and Plcamydin and (2) a safe and effective amount of a N-chlorophenylcarbamate of the formula: ##STR6## wherein n is 1; X is oxygen and wherein R is selected from the group consisting of lower alkyl having from 1 to 4 carbons and pharmaceutically acceptable inorganic or organic acid salts of these compounds. 14. A pharmaceutical composition according to claim 13 comprising a pharmaceutically acceptable carrier and a safe and effective amount of N-chlorophenylcarbamate. 15. A pharmaceutical composition according to claim 14 wherein said pharmaceutically acceptable salts are selected from the group consisting of hydrochlorides, acetates, salicylates, nitrates and phosphate salts and mixtures thereof. 16. A pharmaceutical composition for treating cancer comprising a safe and effective amount of 3-(chlorophenyl)carbamic acid 1-methylethyl ester and a safe and effective amount of taxol.
