The present invention relates to the albumin-guided development of coumarin analogs and the analogs developed thereby. The coumarin analogs of the present invention are identified and isolated by the fact that they have binding sites to albumin which are different than the binding sites of conventional coumarin analogs such as sodium warfarin, and as a result will be less prone to be displaced since the binding site of sodium warfarin is shared by numerous drugs such as aspirin. The coumarin analogs of the invention are advantageous because they can achieve the effects of the prior coumarin analogs with a minimum of metabolic complications and undesirable side effects.
