have the meanings indicated in the specification. These compounds are receptor tyrosine kinase EphB4 inhibitors useful for the treatment of angiogenesis dependent cancers and intraocular neovascular syndromes. The invention further relates to a method termed ALTA (anchor-based library tailoring) of selecting compounds from a large compound library for screening as EphB4 inhibitors by computational procedures.
