Agents having cytotoxic activity, as well as compositions, uses, and methods relating thereto, are described herein. Certain steroid acid-peptide conjugates or moieties have the ability to induce killing or inhibition of proliferation of mammalian cells, in vitro or in vivo upon administration to a subject. The steroid acid-peptide conjugates include bile acids and bile acid analogs and peptides that may include a nuclear localisation signal or a portion thereof. Also described herein is a method for treating cancer, an autoimmune disease, or any other disease or disorder ameliorated by treatment with an antiproliferative drug in a subject in a subject with the cytotoxic agents described herein.

The present invention generally relates to artemisinin/dihydroartemisinin (DHA) derivatives, and their use for therapy, in particular cancer therapy. These tumor-homing artemisinin derivatives (THAD) comprise three moieties: an artemisinin/DHA or a derivative thereof, a heptamethine carbocyanine dye (HMCD) residue, and a linker that conjugates the HMCD dye residue to the artemisinin residue. The THAD include compounds wherein the linker is linked to one or two DHA residue(s) via one or more ether bonds, and wherein the linker is linked to two DHA residues via two bonds independently selected from ester, carbamate and thiocarbamate. The THAD of the invention provide improved growth inhibition of cancer cells. The present invention also relates to improved methods of cancer therapy wherein a THAD is administered to a cancer patient. In embodiments, one or more THAD may be co-administered in a coordinated administration schedule. Advantages of the THAD and their use include, among others, improved dose-response and/or efficacy. The invention also relates to new dyes, their drug conjugates, and processes of making them.
