The invention provides novel solid supports for the synthesis of compound libraries. The solid supports have the physical capacity to deliver at least 50 nmol of compound and are functionalized with a silicon-containing linker. In one embodiment of the invention the solid support comprises a bead having a diameter of between approximately 400 and 600 &mgr;m functionalized with a silicon-containing linker. According to certain embodiments of the invention the bead is a polystyrene bead. According to certain embodiments of the invention the linker is a diisopropylalkyl-substituted silyl ether. The invention further provides grafted polymeric supports such as lanterns functionalized with a silicon-containing linker.
The invention provides methods for screening in which compounds are synthesized on solid supports in a quantity so that a single solid support such as a bead provides a stock solution sufficient to perform hundreds or thousands of biological or chemical assays. The methods include decoding the sequence of chemical reactions used to synthesize the compound by identifying tags incorporated into the compound during synthesis.
本发明提供了用于合成化合物库的新型固体支持体。这些固体支持体具有物理容量,能够提供至少50纳摩尔的化合物,并且具有含
硅连接剂的功能化。在本发明的一个实施例中,固体支持体包括一个直径在大约400到600微米之间的珠子,功能化了含
硅连接剂。根据本发明的某些实施例,珠子是聚
