发现了一系列5,11-二氢-6 H-苯并[ e ]嘧啶[5,4- b ] [1,4]二氮杂-6-酮类作为选择性PI3K-δ/γ抑制剂
摘要:
PI3K-δ和PI3K-γ的双重抑制是血液恶性肿瘤的既定治疗策略。报道的选择性靶向PI3K-δ/γ的分子在化学上是相似的,并且基于异喹啉-1(2 H)-one或喹唑啉-4(3 H)-one支架。在这里,我们报告了基于5,11-二氢-6 H-苯并[ e ]嘧啶[5,4- b ] [1,4]二氮杂-6-的一系列有效的,选择性的PI3K-δ/γ抑制剂一种支架具有可比的生化效能和对PI3K信号传导的细胞作用。我们设想这些分子将为开发下一代PI3K-δ/γ靶向治疗剂提供有用的线索。

A remarkable synergistic effect has been uncovered between ppm levels of Pd and Ni embedded within iron nanoparticles that leads to mild and selective catalytic reductions of nitro-containing aromatics and heteroaromatics in water at room temperature. NaBH4 serves as the source of inexpensive hydride. Broad substrate scope is documented, along with several other features including: low catalyst loading

Heterocyclic compounds as CDK4 or CDK6 or other CDK inhibitors are provided. The compounds may find use as therapeutic agents for the treatment of diseases and may find particular use in oncology.
A new series of benzene and isoquinoline sulfonamide derivatives were synthesized by nucleophilicdisplacement reaction on benzene and isoquinoline sulfonyl chlorides by substituted amines (primary and secondary). The title compounds were evaluated for antimalarial activity against Plasmodium falciparum in vitro and showed MIC in the range of 2-50 microg/mL.

Pharmaceutical compositions containing effective amounts of CDK-inhibiting diaminothiazole compounds of the following formula (where R
1
and R
2
are as defined in the specification) or their salts, or prodrugs or active metabolites of such compounds or salts, are useful for treating disorders and diseases such as cancer:

In preferred embodiments, R
1
and R

are independently unsubstituted or substituted carbocyclic or heterocyclic aryl ring structures. Compounds where R
2
is ortho-substituted aryl are especially potent inhibitors of CDKs such as CDK4.
