Drug binding is Tau-register matching, not shape complementarity

A drug binds selectively when its pharmacophore Tau-modes resonate with the receptor's active-site Tau-modes. Lipinski's 500 Da limit = the {2,3,5} Tau-permeability threshold.

The Framework

Pharmacology is Tau-register engineering

Drug-receptor binding is Tau-register matching. High affinity = high Tau-register resonance. Selectivity = the Tau-mode pattern matches only one receptor. Toxicity = off-target Tau-register matching. Resistance = Tau-register drift in the pathogen.

P-MCHEM-3 — Michaelis-Menten as Tau-saturation
v = V_max × [S] / (K_M + [S])
V_max = maximum Tau-throughput (enzyme fully coupled)
K_M = Tau-mode half-saturation density
At [S]=K_M: v = V_max/2 (50% Tau-mode occupancy)
Key Propositions

Lipinski's Rule of Five is a Tau-permeability law

P-MCHEM-6

MW ≤ 500 = 2²×5³: the binary-quintic Tau-permeability threshold for membrane crossing. logP ≤ 5: Tau-coupling maintained in aqueous register. These are not empirical rules — they are lattice structural limits.

P-MCHEM-7

FOT drug design: map the target receptor's Tau-register, design a pharmacophore whose Tau-mode pattern is the complementary match, verify no off-target register shares the pattern. Replaces empirical SAR with structural Tau-register mapping.
