To explore candidate fungicides from plant secondary metabolites, 16 novel obovatol-type phenazine derivatives were semi-synthesized from obovatol isolated from the leaves of Magnolia obovata Thunb. The antifungal activity of synthesized compounds was investigated in vitro against four phytopathogenic fungi using the spore germination method. The bioassay results showed that eight derivatives exhibited better antifungal activity against Fusarium solani than two pos. controls, especially compounds 3-allyl-1-(4-allylphenoxy)-7,8-difluorophenazine (IC₅₀ = 64.61μg mL-1) and 3-allyl-1-(4-allylphenoxy)-8-chlorophenazine (IC₅₀ = 79.97μg mL-1) showed pronounced inhibition of spore germination activity against F. solani. They could be used as lead compounds for further structural optimization. Addnl., the preliminary structure-activity relationships (SARs) illustrated that the introduction of a benzene ring monosubstituted with electron-withdrawing groups into the obovatol scaffold could lead to potentially antifungal compounds

Adenosine is an immunosuppressive factor in the tumor microenvironment mainly through activation of the A_2A adenosine receptor (A_2AR), which is a mechanism hijacked by tumors to escape immune surveillance. Small-mol. A_2AR antagonists are being evaluated in clin. trials as immunotherapeutic agents, but their efficacy is limited as standalone therapies. To enhance the antitumor effects of A_2AR antagonists, dual-acting compounds incorporating A_2AR antagonism and histone deacetylase (HDAC) inhibitory actions were designed and synthesized, based on co-crystal structures of A_2AR. Compound 24e (IHCH-3064) exhibited potent binding to A_2AR (K_i = 2.2 nM) and selective inhibition of HDAC1 (IC₅₀ = 80.2 nM), with good antiproliferative activity against tumor cell lines in vitro. I.p. administration of 24e (60 mg/kg, bid) inhibited mouse MC38 tumor growth with a tumor growth inhibition rate of 95.3%.

Yan, Dan;Zhang, Haili;Xu, Xiao;Ren, Chunling;Han, Chao;Li, Zhongrui research published 《 Theranostic nanosystem with supramolecular self-assembly for enhanced reactive oxygen species-mediated apoptosis guided by dual-modality tumor imaging》, the research content is summarized as follows. With the development of precision medicine, visual and traceable treatments are highly desirable for cancer therapy. However, researchers and clinicians remain confused regarding where the drug distributes and location of the tumor, when the drug is released and when to irradiate the tumor, and how the drug presents antitumor activity, all of which hinders assessment of the cancer patient′s condition and formulation of a follow-up treatment scheme for clinicians. Here, a supramol. self-assembly theranostic nanosystem (MWNs) was designed for enhanced reactive oxygen species (ROS)-mediated cell apoptosis guided by dual-modality tumor imaging. Specifically, merocyanine was introduced in cyanine dye to extend its conjugated π-scaffolds, which could preferentially self-assemble into nanovesicles owing to its amphipathy. Furthermore, withaferin A (WA), used as a chemotherapeutic drug, was loaded to construct MWNs. The assembled or disassembled MWNs behaved differently in photoacoustic (PA) intensity and fluorescence signal intensity. The MWNs exhibited stronger PA signals and quenched fluorescence, which monitors their distribution and images the tumor location in vivo, while the disassembled MWNs showed weak PA signals and recovered fluorescence, indicating the release of drug and instructing the appropriate time to irradiate for photodynamic therapy (PDT). Thus, ROS generation introduced by PDT and released WA led to cell apoptosis. This intelligent nanosystem for precise cancer therapy that reveals where the tumor is, when to irradiate the tumor, and how the tumor is cured might establish the basis for biomedical applications of finely controlled platform.
