The present invention relates to the compositions, methods, and applications of a new approach to pattern recognition based targeting by which an exponential amplification of effector response can be specifically obtained at a targeted cells. The purpose of this invention is to enable the selective delivery of large quantities of an array of effector molecules to target cells for diagnostic or therapeutic purposes. The invention is comprised of two components designated as "Compound 1" and "Compound 2": Compound 1 is comprised of a cell binding agent and a masked female adaptor. Compound 2 is comprised of a male ligand, an effector agent, and two or more masked female receptors. The male ligand is selected to bind with high affinity to the female adaptor. Compound 1 can bind with high affinity to the target cell and the female receptor can then be unmasked by an enzyme enriched at the tumor cell. The male ligand of Compound 2 can then bind to the unmasked female adaptor bound to the target cell. The masked female adaptor on the bound Compound 2 can then be specifically unmasked. One receptor has in effect become two. Two new molecules of Compound 2 can bind to the unmasked adaptors receptors. After unmasking two receptors in effect become four. The process can continue in an explosive exponential like fashion resulting in enormous amplification of the number of effector molecules specifically deposited at the target cell.

A method for differential drug discovery involves obtaining a receptor panel. The receptor panel specifies a multitude of targets and a multitude of anti- targets. The method further involves obtaining a small molecule compound (SMC) seed model and derivatizing a first multitude of candidate SMCs from the SMC seed model.
