Huh? Crixivan is C36H47N5O4-H2O4S. Viracept is C32H45N3O4S-CH4O3S. Not a big diffrence in "molecular size" there. Neither is a particularly small molecule -- that term is usually reserved for molecules with molecular weights less than 400-500, and both Viracept and Crixivan beat that by a lot.

There is nothing about the molecular structure of these molecules that would have anticipated this problem. It is certainly safe to assume that the "buffalo hump" effect will be different for the various PI's, but that difference will have to come from empirical observations in the clinic rather than guesses from molecular structure.

Just curious: what part of either molecule do you consider to be "extraneous"?
