The synthesis and in vitro cytotoxic characteristics of new imidazo[1,2‐b]pyrazole‐7‐carboxamides were investigated. Following a hit‐to‐lead optimization exploiting 2D and 3D cultures of MCF‐7 human breast, 4T1 mammary gland, and HL‐60 human promyelocytic leukemia cancer cell lines, a 67‐membered library was constructed and the structure–activity relationship (SAR) was determined. Seven synthesized
New C4- and C1-derivatives of furo[3,4-c]pyridine-3-ones and related compounds: Evidence for site-specific inhibition of the constitutive proteasome and its immunoisoform
furo[3,4-c]pyridine-3-one), 6 model compounds (γ- and δ-lactones) and 20 furo- or thieno[2,3-d]-pyrimidine-4-one relatedcompounds were designed and synthesized. Each compound was assayed for inhibition of CT-L, T-L and PA proteolytic activities of 20S constitutive proteasome (c20S). Most performant compounds were also assayed on 20S immunoproteasome (i20S). Compound 10 with a benzylamino group at C4

The most promising compound (3) has shown activity in rat and mouse collagen (II)-induced arthritis models (ED50 = 2 and 31 mg/kg, respectively) and has shown a shorter half-life in man when compared with leflunomide.

Novel derivatives of isothiazoles are described as potent ATP-competitive inhibitors of vascular endothelial growth factor receptors I and II (VEGFR-1/2). A number of compounds exhibited VEGFR-2 inhibitory activity comparable to that of Vatalanib™ in both HTRF enzymatic and cellular assays. Several derivatives featuring bulky meta-substituents in the amide portion of the molecule displayed 4- to 8-fold
异噻唑的新型衍生物被描述为血管内皮生长因子受体I和II(VEGFR-1 / 2)的有效ATP竞争性抑制剂。在HTRF酶和细胞分析中,许多化合物均具有与Vatalanib™相当的VEGFR-2抑制活性。几种在分子的酰胺部分具有较大的间位取代基的衍生物显示出对VEGFR-2的特异性是VEGFR-1的4到8倍。活性分子 在整个Caco-2细胞单层上也表现出高的固有渗透性(> 30×10 -5 cm / min)。
