dinyl)-7-(indol-3-ylcarbonyl)-1H-3H-pyrrolo[1,2-c] thiazoles represent
a class of potent, orally active PAF antagonists; however, the lead c
ompounds in this series suffered from a lack of aqueous solubility. To
overcome this limitation, a number of strategies were examined to ach
ieve improved solubility, involving the incorporation of polar substit
uents and the use of prodrugs.
