The synthesis of a novel class of macrocyclic bis(indolylmaleimides) is reported. The key step involves the intermolecular connection of 2,2′-bridged indoles with 3,4-dibromo-2,5-dihydro-1H-2,5-pyrroledione (dibromomaleimide) derivatives. The bis(indolylmaleimides) afforded by this method were further processed by intramolecular nucleophilic substitution of the remaining bromo substituents forming

Described herein are compounds capable of modulating one or more biomolecules substantially simultaneously, e.g., modulating two or more binding domains (e.g., bromodomains) on a protein or on different proteins. For example, in one aspect, a bivalent compound or a pharmaceutically acceptable salt, stereoisomer, metabolite, or hydrate thereof is provided. In another aspect, a method of treating a disease associated with a protein having tandem bromodomains in a patient in need thereof is provided. The method comprises administering to the patient the bivalent compound as described.

The invention pertains to a process for manufacturing alkyleneamine compounds, comprising the steps of - in a reaction medium reacting an alkyleneurea compound comprising at least one primary amine group, or at least one cyclic secondary amine group, or at least one primary amine group and at least one cyclic secondary amine group, and at least one cyclic alkyleneurea group of formula I wherein A is selected from the group of C2 to C4 alkylene units, optionally substituted by one or more C1 to C3 alkyl groups, with an alkylhalide compound to form an alkyleneamine hydrohalide salt comprising at least one cyclic alkyleneurea group of formula I, the alkylhalide compound being selected from the group of haloalkanes with 2-6 halogen atoms, and haloaminoalkanes, and - reacting the alkyleneamine hydrohalide salt with a base to form an alkyleneamine compound comprising at least one cyclic alkyleneurea group of formula I. In one embodiment the reaction is carried out in the presence of one or more of ammonia and additional alkyleneamine compound. The process according to the invention produces less cyclic and branched side products and more straight-chain higher alkyleneamines than conventional processes, in particular more straight-chain ethyleneamines selected from L-TETA, L-TEPA, and L-PEHA.
The present invention provides compounds of formula M-L-M′ (where M and M′ are each independently a monomeric moiety of Formula (I) and L is a linker). The dimeric compounds have been found to be effective in promoting apoptosis in rapidly dividing cells.
