Abstract: Disclosed is a method of treating cell proliferative disorders, such as cancer, with amounts of chlorotoxin and/or derivatives, analogs or fragments thereof, which are effective to bind to phosphoinositol phospholipids.

Abstract: The present invention is directed to methods and compositions for the treatment and diagnosis of neuroectodermally-derived tumors, such as gliomas. The inventive methods of treatment generally include local (e.g., intracavitary) administration of a chloroxotoxin moiety conjugated to a cytotoxic moiety to a patient. Also provided are diagnostic methods for screening neoplastic neuroectodermal tumors.

Abstract: This invention relates to proteins (e.g., peptides) that are capable of facilitating transport of an active agent through a human or animal gastro-intestinal tissue, and derivatives (e.g., fragments) and analogs thereof, and nucleotide sequences coding for said proteins and derivatives. The proteins of the invention have use in facilitating transport of active agents from the lumenal side of the GIT into the systemic blood system, and/or in targeting active agents to the GIT. Thus, for example, by binding (covalently or noncovalently) a protein of the invention to an orally administered drug, the drug can be targeted to specific receptor sites or transport pathways which are known to operate in the human gastrointestinal tract, thus facilitating its absorption into the systemic system.

Abstract: Disclosed is a method of treating cell proliferative disorders, such as cancer, with low doses of chlorotoxin and/or derivatives, analogs or fragments thereof, which are effective to inhibit or arrest abnormal cell growth.

Abstract: This invention includes compositions and methods for combination chemotherapy, particularly involving at least one chemotherapeutic agent used in combination with chlorotoxin or a derivative thereof.
