The present invention relates to a chemotherapeutic
cancer treatment in which compounds of Formula Ia′, Ib′, Ic′, or II′ (referred to as a group as BH3Is) are administered to a
mammal for the treatment of B-
cell Lymphoma or other hematopoietic cancers, including diseases associated with MCL-1. In another aspect, the invention provides a method for treating particular types of hematopoietic cancers, such as B-
cell lymphoma, using a combination of one or more compounds selected from the group consisting of compounds or Formula Ia, Ib, Ic, or II in combination with other therapies, for example, a class of therapeutics known as 26S proteosome inhibitors, such as, for example,
Bortezomib. In another aspect the present invention relates to autoimmune treatment with pharmaceutical compositions comprising one or more compounds of Formula Ia′, Ib′, Ic′, or II′. In another aspect, this invention relates to methods for identifying compounds, for example, compounds of the BH3 mimic class, that have unique
in vitro properties that predict
in vivo efficacy against B-
cell lymphoma tumors and other cancers as well as
autoimmune disease.
