In an embodiment of the invention, a composition for treating a cell population comprises an Affinity Medicant Conjugate (AMC). The medicant moiety can be a toxin including an acylfulvene or a drug moiety. The affinity moiety can be an antibody, a binding protein, a steroid, a lipid, a growth factor, a protein, a peptide or non peptidic. The affinity moiety can be covalently bound to the medicant via a linker. Novel linkers that can be directed to cysteine, arginine or lysine residues based on solution pH allow greater flexibility in preserving and/or generating specific epitopes in the AMC.

Affinity medicant conjugate

In an embodiment of the invention, a composition for treating a cell population comprises a medicant. The medicant moiety can be an illudofulvene analog. In an embodiment of the invention, a composition for treating a cell population comprises an Affinity Medicant Conjugate (AMC). The affinity moiety can be an antibody, an antibody fragment, a receptor protein, a peptidic growth factor, an anti-angiogenic protein, a specific binding peptide, protease cleavable peptide, a glycopeptide, a peptide, a peptidic toxin, a protein toxin and an oligonucleotide. The affinity moiety can be covalently bound to the medicant via a linker.

Affinity illudofulvene conjugates

In an embodiment of the invention, a method of treating cancer includes screening to select a patient population that will respond to an Illudofulvene Analog composition based on the presence of one or more Transcription Coupled Repair (TCR) mutations, deletions or other events interfering with TCR biomarker expression in combination with upregulation of Myc and/or PTGR biomarker expression and treating the patient population with the Illudofulvene Analog composition.

The present invention provides illudin analogs of the general formula (I): 

Illudin analogs useful as antitumor agents

Acylfulvene analogs, which inhibit tumor growth, especially solid tumor growth, and which have an adequate therapeutic index to be effective for in vivo treatment are provided herein. The compounds described herein are useful as anti-neoplastic agents, i.e., to inhibit tumor cell growth in vitro or in vivo, in mammalian hosts, such as humans or animals, e.g., domestic animals, and are effective against solid tumors, hematologic malignancies and multi-drug resistant cancers/tumors. The present compounds can be used alone or they can be used in combination with one or more anti-cancer or anti-tumor agents.

Illudin analogs useful as anticancer agents

The present invention provides compounds of the general formula I: wherein R, R, R, R, R, and Rhave any of the values defined in the specification, and pharmaceutically acceptable salts thereof, as well as pharmaceutical compositions comprising compounds of formula I, intermediates and processes useful for preparing compounds of formula I, and methods comprising inhibiting tumor growth or treating cancer by administering one or more compounds of formula I.
