Ethane-1,2-diylbis(oxy)bis(ethane-2,1-diyl)bis(bis(thiophene-2ylmethyl)carbamate (C1) is a representative small molecule, poorly water-soluble pharmaceutical integrin agonist adjuvant agent with desired pharmacologic properties. However, C1 has limited by aqueous solubility and oral bioavailability. To improve oral absorption, lipid-based carrier compositions have been formulated, and methods to manufacture oral dose forms to reach optimal pharmacokinetic exposures.
Pharmaceutical integrin agonist adjuvant agents of low water solubility, for example those classified as “practically insoluble” or “insoluble” according to United States Pharmacopeia (USP) 24 (2000), p. 10, i.e., having solubility of less than about 1 part per 10,000 parts water (less than about 100 ug/ml) are notoriously difficult to formulate for oral delivery. Among other problems, bioavailability of such drugs, when administered by the oral route, tends to be very low. The oral bioavailability is further confounded by the fact that these molecules have molecular weights >500, without ionizable group, and are metabolized by gastrointestinal mucosal and hepatic CYP45b enzymes.
