Two novel DNA-direct alkylating agents, consisting of aniline mustard linked to an angular 3H-pyrrolo[3,2-f]quinoline nucleus, were synthetized and assayed for their in vitro antiproliferative activity. Simple convergent synthesis, consisting of separate preparation of 9-chloro-3H-pyrrolo[3,2-f]quinoline and p-amino-aniline derivatives, and following their linkage by substitution reactions 8a, b and 10, yielded the corresponding diol derivatives 7b and 9. Biological properties were evaluated with respect to cell growth inhibition, ability to form cross-links with DNA, and capacity to give rise to a molecular complex with the macromolecule for 7b, 8b, 9 and 10.

The labile tautomerism of -unsubstituted 5-acyl-4-pyridones, which exist in the form of 4-pyridone or 4-hydroxypyridine depending on the solvent, has been demonstrated. This equilibrium determines the reactivity of pyridones and their ability to undergo substitution reactions of the OH group. A regioselective and convenient method for the construction of functionalized pyrazolo[4,3-]pyridines (30-93%) based on the intramolecular amination reaction of 4-pyridones with hydrazines has been developed.

This study aimed to design a novel liposome containing GA modified phosphatidylcholine lipid (GA-PC Lip) and determine its susceptibility to tumor over-expressed secretory phospholipase A (sPLA) and its anti-cancer effect compared to conventional liposomes (Convention Lip). The liposomes were characterized for size, drug loading, encapsulation efficiency, and stability. A 6-CF release assay was conducted to assess the sensitivity of the liposomes to the tumor-overexpressed secretory phospholipase A (sPLA).

The role of the electron transport chain (ETC) in cell proliferation control beyond its crucial function in supporting ATP generation has recently emerged. In this study, we found that, among the four ETC complexes, the complex I (CI)-mediated NAD regeneration is important for cancer cell proliferation. In cancer cells, a decrease in CI activity by RNA interference (RNAi) against NADH:ubiquinone oxidoreductase core subunit V1 (NDUFV1) arrested the cell cycle at the G/S phase, accompanying upregulation of p21 cyclin-dependent kinase inhibitor expression.

Histone deacetylase 3 (HDAC3) is a well-established target for cancer therapy. Herein, we developed as a novel HDAC3 inhibitor, which exhibited high HDAC3 inhibitory activity (IC = 42 nM, SI > 161) and displayed potent antiproliferative activity against four cancer cells and further demonstrated excellent antimigratory, anti-invasive, and antiwound healing activities. Further studies revealed that induced a dose-dependent increase in Ac-H3 expression and promoted the degradation of PD-L1.

Estrogen receptor β (ERβ) is aberrantly expressed in castration-resistant prostate cancer (CRPC). Therefore, a diagnostic and therapeutic ERβ probe not only helps to reveal the complex role of ERβ in prostate cancer (PCa), but also promotes ERβ-targeted PCa therapy. Herein, we reported a novel ERβ-targeted near-infrared fluorescent probe D3 with both imaging and therapeutic functions, which had the advantages of high ERβ selectivity, good optical performance, and strong anti-interference ability.
