  • Patent number: 10975412
    Abstract: A method is described for the identification of multi-subunit biocomplex drug targets. The method includes identifying a target that performs a biological function, wherein the target comprises one or more subunits, wherein a minimum number of the one or more subunits is inactivated to inhibit the biological function. The method includes selecting a drug that binds specifically to each subunit of the one or more subunits with a target probability. The method describes a relationship between inhibition efficiency of the drug and total number of the one or more subunits using a binomial distribution, wherein the inhibition efficiency comprises a probability that the delivered drug blocks the biological function. The method includes confirming empirically the relationship using an experimental target. The method includes administering the drug to the target to treat a multi-drug resistant disease, wherein the target comprises a biological complex in a mammalian subject.
