Abstract: Beta-lapachone, which is poorly soluble in most pharmaceutically acceptable solvents, has demonstrated significant antineoplastic activity against human cancer lines. The present invention overcomes this significant limitation by teaching novel pharmaceutical compositions comprising a therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, and a pharmaceutically acceptable solubilizing carrier molecule, which may be at water-solubilizing carrier molecule such as hydroxypropyl-?-cyclodextrin, or an oil-based solubilizing carrier molecule, for enhancing the solubility of Beta-lapachone in aqueous solution. The therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, may be complexed with the pharmaceutically acceptable solubilizing carrier molecule in aqueous solution. The novel pharmaceutical compositions may be administered with a second anticancer agent or in combination with radiation therapy.

Abstract: This invention relates to novel derivatives of camptothecin, and will, particularly to derivatives having a substitution at the C-7 position, or at one of the C-9, C-10, C-11 or C-12 positions, or to disubstituted derivatives having a first substitution at C-7 and a second at one of C-9, C-10, C-11 or C-12. The invention also includes methods of using the compounds as Topoisomerase I inhibitors to treat patients with cancer. The invention also includes pharmaceutical formulations which consist of the novel compounds in solution or suspension with one or more pharmaceutical excipients or dilutes.

Abstract: To reduce the toxic effect of carboplatin, particularly myelosuppression and emesis, a dithioether having the formula R.sub.1 -(CH.sub.2).sub.n --S--S--(CH.sub.2).sub.m --R.sub.2 (I) wherein:each of R.sub.1 and R.sub.2 individually is SO.sub.3 H or PO.sub.3 H.sub.2 ; andeach of m and n is individually 1, 2, 3 or 4;or a pharmaceutically acceptable salt thereof, preferably disodium 2,2'-dithiobis(ethane sulfonate) (dimesna), is administered in combination with carboplatin to a patient, at substantially the same time or sequentially, whereby the dithioether and the carboplatin become co-present in the blood of the patient. Compositions comprising carboplatin and the dithioether are included in the invention.
