Provided herein are compounds of the Formula I and stereoisomers and pharmaceutically acceptable salts or solvates thereof, in which A, B, X1, X2, X3, X4, Ring D, and E have the meanings given in the specification, which are inhibitors of RET kinase and are useful in the treatment and prevention of diseases which can be treated with a RET kinase inhibitor, including RET-associated diseases and disorders.
Enzymatic synthesis of 2-hydroxy-4<i>H</i>-quinolizin-4-one scaffolds by integrating coenzyme a ligases and a type III PKS from <i>Huperzia serrata</i>
2-Hydroxy-4H-quinolizin-4-one scaffolds were enzymatically synthesized by integrating three enzymes including phenylacetate-CoA ligase (PcPCL) from an endophytic fungus Penicillium chrysogenum MT-12, malonyl-CoA synthase (AtMatB) from Arabidopsis thaliana, and a type III polyketide synthase (HsPKS3) from Chinese club moss Huperzia serrata. The findings paved the way to produce these kinds of structurally
2-Hydroxy-4 H -quinolizin-4-one 支架是通过整合三种酶来酶促合成的,包括来自内生真菌Penicillium chrysogenum MT-12的苯乙酸-CoA 连接酶 (PcPCL )、来自拟南芥的丙二酰-CoA 合酶 (AtMatB)和一种来自中国石杉石杉的 III 型聚酮合酶 (HsPKS3) 。这些发现为通过工程微生物生产这些结构上有趣的生物碱铺平了道路。
