由于其天然毒性,天然伊兰度作为其抗肿瘤剂的兴趣有限。为了开发其细胞毒性潜力,已经合成了几种衍生物以获得具有改善的治疗指数的化合物。在本文中,我们描述了一些烷基化和氧化反应在某些情况下会产生较少的细胞毒性衍生物。结构和相对立体化学是根据1 H和13 C NMR证据。所有化合物的细胞毒性均不如illudin M和S,但仍具有很高的活性。
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.

The present invention relates to compositions, methods and devices for treating cancer with illudofulvenes including methods to detect the expression levels of genes encoding biomarkers in cancer patients and to predict the responsiveness of cancer patients to illudofulvenes.
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.

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.
