Valine-containing protein (VCP) is a member of the adenosine triphosphate family involved in a variety of cellular activities. VCP/p97 is capable of maintaining protein homeostasis and mediating the degradation of misfolded polypeptides by the ubiquitin–proteasome system (UPS). In this manuscript, a series of novel p97 inhibitors with pyrimidine as core structure were designed, synthesized and biologically evaluated. Based on the enzymatic results, a detailed structure–activity relationship discussion of the synthesized compounds was carried out. Furthermore, cellular activities of the compounds with enzymatic potency of less than 200 nM were investigated by using A549 and RPMI8226 cell lines. Among the screened inhibitors, compound 17 (IC50, 54.7 nM) showed good enzymatic activity. Investigation of cellular activities with non-small cell lung cancer A549 and multiple myeloma (MM) RPMI8226 further confirmed the potency of 17 with the IC50 values of 2.80 μM and 0.86 μM, respectively. Compound 17 is now being developed as a candidate. Finally, docking studies were carried out to explore the possible binding mode between the active inhibitor 17 and p97.

In the present work, we demonstrated a simple and an efficient method for the condensation of substituted aryl/heteroaryl amines with acetonylacetone in the presence of trifluoro acetic acid to afford the corresponding 2,5-dimethyl-1-substitued pyrroles using Paal-Knorr synthesis in excellent yields. Trifluoroacetic acid was used under reflux condition for the deprotection of 2,5-dimethyl-1-substitued pyrroles to their corresponding substituted aryl/heteroaryl amines in moderate yields. 2,5-Dimethyl-1-substitued pyrrole were characterized by NMR and LC-MS. The yield of the compounds was found to be excellent.

This work investigated the in vitro and in vivo anti-angiogenic activity of some pyrroloazaflavones, exactly 2-phenyl-1H-pyrrolo[2,3-h]quinolin-4(7H)ones, with vinblastine as reference compound. Growth inhibitory activity, migration, and capillary-like structures formation were determined in human umbilical vein endothelial cell cultures, and Matrigel plug assay was carried out to evaluate in vivo effects on angiogenesis. Collectively, our results indicate that some pyrroloazaflavone derivatives, at non-cytotoxic concentrations and like vinblastine are able: (i) to exert in vitro anti-angiogenic activity and (ii) to counteract in vitro and in vivo the pro-angiogenic effects of fibroblast growth factor-2 (FGF-2).

New series of indazoles substituted at the N-1 and N-2 positions and their 7-ethoxy derivatives have been synthesis starting from alkylation of 4-nitroindazole and reduction of alkyl-nitro-derivatives with anhydrous SnCl2 in ethanol. The structures of the
