肿瘤相关的巨噬细胞(TAM)主要与肿瘤的生长有关。集落刺激因子1受体(CSF1R)充当TAM存活和分化的关键调节剂,并且是癌症治疗的分子靶标。本文中,通过铰链结合部分的替代策略鉴定了新型CSF1R抑制剂。咪唑并[1,2- a ]吡啶(49)或吡唑并[1,5- a ]吡啶(50)作为铰链粘合剂的引入在酶法测定中对CSF1R在10 nM抑制率分别为87%和82%。 IC 50在MNFS60单元中分别为25 nM和27 nM的值。这些衍生物显着抑制细胞中的CSF1R磷酸化。我们的方法可以用作发现新型激酶抑制剂的策略。
Provided herein are heterocyclic derivative compounds and pharmaceutical compositions comprising said compounds that are useful for inhibiting plasma kallikrein. Furthermore, the subject compounds and compositions are useful for the treatment of diseases wherein the inhibition of plasma kallikrein inhibition has been implicated, such as angioedema and the like.
hygroscopicus, the geldanamycin producer, with 21 aromatic and heteroaromatic amino acids provided new nonquinoid geldanamycin derivatives. Large scale (5 L) fermentation provided four newderivatives in sufficient quantity for full structural characterisation. Among these, the first thiophene derivative of reblastatin showed strong antiproliferative activity towards several human cancer cell lines.

A number of 5-oxo-2,5-dihydroisoxazoles, substituted with nitrogen heterocycles at N-2, have been subjected to flashvacuumpyrolysis. Annelated imidazoles are obtained in excellent yields, and are presumed to arise by intramolecular cyclisation of an imino carbene intermediate. The heterocycles annelated in this manner include isoquinoline, quinoline, benzothiazole, quinazoline, phenanthridine, pyrimidine
