A series of pyrido[2,3-d]pyrimidine derivatives were easily constructed by cyclocondensation reactions of 6-aminouracils or 6-aminothiouracil with α,β-unsaturated carbonyl compounds (aldehyde, ketone and ester) possessing a leaving group on the β position, in H2O under reflux conditions.
通过6-氨基尿嘧啶或6-氨基硫尿嘧啶与在β位上具有离去基团的α,β-不饱和羰基化合物(醛,酮和酯)的环缩合反应,可轻松构建一系列吡啶并[2,3- d ]嘧啶衍生物,在回流条件下在H 2 O中。

A monomer useful in prepaπng therapeutic compounds includes a diversity element which potentially binds to a target molecule with a dissociation constant of less than 300 11 M and a linker element connected to the diversity element The linker element has a molecular weight less than 500 daltons, is connected, directly or indirectly through a connector, to said diversity element, and is capable of forming a reversible covalent bond or noncovalent interaction with a binding partner of the linker element The monomers can be covalently or non-covalently linked together to form a therapeutic multimer or a precursor thereof
