What is the Origin of Chemical Sequestration Bypass?

This concept is rooted in the understanding of steroid hormone transport, where plasma proteins like SHBG and albumin significantly reduce the free fraction of the hormone. The term describes the deliberate development of agents or delivery methods that circumvent this natural binding phenomenon. Medicinal chemists use this approach to design molecules with lower affinity for carrier proteins.

What is the Mechanism of Chemical Sequestration Bypass?

One primary mechanism involves modifying the chemical structure of the therapeutic molecule to reduce its binding affinity for high-capacity carrier proteins such as Sex Hormone Binding Globulin (SHBG). Alternatively, the compound may be delivered via a route that temporarily saturates the binding sites, such as high-concentration transdermal application, allowing a surge of the free molecule into the circulation. The net effect is a transient or sustained increase in the biologically active, unbound concentration.

Chemical Sequestration Bypass

Meaning

Chemical sequestration bypass refers to pharmaceutical or formulation strategies designed to prevent a therapeutic compound, often a hormone or active metabolite, from being bound or trapped by endogenous circulating proteins or other biological molecules. This strategic maneuver ensures a higher proportion of the administered agent remains in the free, biologically active state within the bloodstream. Bypassing sequestration is critical for maximizing the therapeutic potency of the dosage.
