Variable Region<br />

Constant Region<br />

v Like Mabs, members of <strong>the</strong> Rapamycin/FK506 family of natural products have a<br />

variable and a constant region<br />

v The variable region confers target specificity; The constant region confers presentation<br />

v Unlike Mabs, <strong>the</strong>se drugs are orally bioavailable and can access intracellular targets<br />
