While expanding the pharmacophoric model of antialphaviral amidines prepared via a quinazolinone rearrangement, we discovered that diamine-treated, 2-dihalomethylquinolinones unexpectedly afforded ring-expanded piperazine-fused benzodiazepinones I [R1 = NO2, F, CN; R2 = H, NO2; R3 = H, Br, 2-morpholinyl, etc.; R4 = Me, Bn; R5 = Me, cyclohexyl, Bn; Ar = Ph, 4-MeOC6H4, 4-FC6H4, etc.]. Notably, this new chemotype showed potent, submicromolar inhibition of virus-induced cell death, >7-log reduction of viral yield, and tractable structure-activity relationships across both viruses. Antiviral activity was confirmed in primary human neuronal cells. A mechanistic rationale for product formation is proposed, and key structural elements were comparatively modeled between a similarly substituted antiviral amidine and piperazinobenzodiazepinone prototypes to guide future antiviral development.

Gao, Ziqing; Mi, Rui; Cheng, Zhaoxi; Li, Xiaofeng; Zeng, Huawu; Wu, Gaosong; Zhao, Jing; Zhang, Weidong; Ye, Ji published the artcile< Integrated metabolomics and network pharmacology revealed Hong-Hua-Xiao-Yao tablet's effect of mediating hormone synthesis in the treatment of mammary gland hyperplasia>, Formula: C19H34O2, the main research area is HHXYT hormone synthesis mammary gland hyperplasia metabolomics network pharmacol; Hong-Hua-Xiao-Yao tablet; mammary gland hyperplasia; metabolomics; network pharmacology; pharmacological effects; traditional medicine.

Hong-Hua-Xiao-Yao Tablet (HHXYT) is a traditional Chinese medicine (TCM) formula that has been approved for the treatment of mammary gland hyperplasia (MGH), but its mechanism of action is unclear. In this study, a strategy that integrated metabolomics and network pharmacol. was applied to systemically reveal the mechanism of HHXYT in the treatment of MGH. Our pharmacodynamic study indicated that the proliferation of mammary gland was inhibited in rats, and serum-level disorder of estradiol and progesterone was reversed after HHXYT treatment. 54 compounds absorbed in rat plasma were identified after administration of HHXYT. The serum metabolome revealed 58 endogenous differential metabolites, of which 31% were steroid lipids metabolites, with steroid hormone biosynthesis being the most significant metabolic module. 7 targets, 6 herbs, and 17 ingredients were found to play key roles in HHXYT’s treatment of MGH. 3 of the 7 key targets (CYP11A1, HSD3B2, and CYP17A1) were directly involved in androgen synthesis, while 2 targets (AR and ESR1) were receptors for the direct action of androgens and estrogens. Mol. docking was utilized to confirm the bindings between the 5 targets and their corresponding compounds In an in vitro test, HHXYT (50μg/mL) and its ingredient formononetin (3.2, 6.3, and 12.5μM) were found to significantly reduce the increase of testosterone level induced by dexamethasone (10μM) in thecal cells. In summary, this study illustrated that the mechanism of HHXYT’s treatment of MGH was to regulate hormone disorder. HHXYT could reduce estrogen-stimulated hyperplasia by inhibiting the production of its precursor androgen.

A macrocyclization approach has been explored on a series of benzoxazine phosphoinositide 3-kinase δ inhibitors, resulting in compounds with improved potency, permeability, and in vivo clearance while maintaining good solubility The thermodn. of binding was explored via surface plasmon resonance, and the binding of lead macrocycle 19 was found to be almost exclusively entropically driven compared with progenitor 18, which demonstrated both enthalpic and entropic contributions. The pharmacokinetics of macrocycle 19 was also explored in vivo, where it showed reduced clearance when compared with the progenitor 18. This work adds to the growing body of evidence that macrocyclization could provide an alternative and complementary approach to the design of small-mol. inhibitors, with the potential to deliver differentiated properties.

Heterocyclic bases as a part of nucleosides and nucleotides are important components of DNA and RNA, and in addition, they take part in a huge number of key metabolic processes, as cofactors or regulators of hundreds of reactions of various types.1 In this regard, any modification of the nucleic base can have a significant effect on the recognition and inhibition of the corresponding enzymes, and, thus, on the spectrum of its activity.1-3 At the moment, analogs and derivatives of nucleic acid components (NA) are important elements of anticancer,1,2,4 antibacterial,5,6 antifungal7,8 and antiviral therapies.1-3,9,10 The antiviral activity of pyrimidine base derivatives has been known since 1963, when it was shown that 20-deoxy-5-iodocytidine inhibits the development of herpesvirus infection.11 Pyrimidine-containing nucleoside analogs became the first drugs for the treatment of infection caused by human immunodeficiency virus type 1 (HIV-1) and are still used in therapy. Zidovudine,12 stavudine,13 lamivudine14,15 and emtricitabine16 are nucleoside inhibitors of HIV-1 reverse transcriptase (NRTI HIV-1). Pyrimidinecontaining analogs of NA components are widely used to treat infections caused by viruses of the herpes group, in particular: brivudine against varicella-zoster virus17 and cidofovir against cytomegalovirus.18 The main mechanism of the antiviral activity of NRTI is intracellular phosphorylation to the corresponding triphosphorylated nucleoside analogs, which then act as

Yu, Haiyang; Gong, Wen; Mei, Junhao; Qin, Lihao; Piao, Zeyu; You, Deshu; Gu, Wenxian; Jia, Zhongzhi published the artcile< The efficacy of a paeoniflorin-sodium alginate-gelatin skin scaffold for the treatment of diabetic wound: An in vivo study in a rat model>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is paeoniflorin sodium alginate gelatin skin scaffold; diabetes wound healing 3D bioprinting; 3D bio-printing; Diabetes; Paeoniflorin; Skin scaffold; Wound.

To investigate the efficacy of a paeoniflorin-sodium alginate (SA)-gelatin skin scaffold for treating diabetic wound in a rat model. Bioinks were prepared using various percentages of paeoniflorin in the total weight of a solution containing SA and gelatin. Skin scaffolds containing 0%, 1%, 3%, 5%, and 10% paeoniflorin were printed using 3D bioprinting technol. and scaffold microstructure was observed with SEM. Skin scaffolds were then used in rats with diabetic wounds. H&E staining, Masson staining, and immunohistochemichal staining for IL-1β and CD31 were performed on days 7 and 14. All skin scaffolds had a mesh-like structure with uniform pore distribution. Wounds healed well in each group, with the 1% and 3% groups demonstrating the most complete healing. H&E staining showed that skin accessory organs had appeared in each group. On day 7, collagen deposition in the 3% group was higher than in the other groups (P<0.05), and IL-1β infiltration was lower in the 10% group than in the 3% group (P = 0.002). On day 14, IL-1β infiltration was not significantly different between the 10% and 3% groups (P = 0.078). The CD31 level was higher in the 3% group than in the other groups on days 7 and 14 (P<0.05). A 3% paeoniflorin-SA-gelatin skin scaffold promoted the healing of diabetic wounds in rats. This scaffold promoted collagen deposition and microvascular regeneration and demonstrated anti-inflammatory properties, suggesting that this scaffold type could be used to treat diabetic wounds.

Ma, Hongen; Hao, Jiping; Liu, Huihui; Yin, Jia; Qiang, Mingmin; Liu, Meilin; He, Shaohui; Zeng, Di; Liu, Xiongtao; Lian, Cheng; Gao, Yuqin published the artcile< Peoniflorin Preconditioning Protects Against Myocardial Ischemia/Reperfusion Injury Through Inhibiting Myocardial Apoptosis: RISK Pathway Involved>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is peoniflorin apoptosis myocardial ischemia reperfusion injury; Ischemia/reperfusion injury; Myocardial apoptosis; Peoniflorin; RISK pathway.

Preconditioning with Peoniflorin, a component of traditional Chinese prescriptions, was proposed to be a potential strategy for cardioprotection against ischemia/reperfusion (I/R) injury. However, the cardioprotective effect of Peoniflorin preconditioning has not been thoroughly confirmed, and the underlying mechanism remains unclear. Here, we examined the cardioprotective effect and its mechanism of Peoniflorin preconditioning against myocardial I/R injury. Rats were subjected to 30 min of transient ischemia followed by 2 h of reperfusion with or without Peoniflorin (100 mg/kg) prior to reperfusion. Peoniflorin preconditioning significantly limited myocardial infarct size and reperfusion arrhythmias, as well as obviously attenuated the histomorphol. and micromorphol. damages induced by I/R injury. The reduced myocardial injury was also associated with the anti-apoptotic effect of Peoniflorin, as evidence by decreased TUNEL-pos. cells, upregulation of BCL-2 expression, and downregulation of Bax and caspase-3 expression. In an effort to evaluate the mechanism responsible for the observed cardioprotective and anti-apoptotic effect, Western blot of phosphorylated protein was performed after 20 min of reperfusion. Results showed that Peoniflorin preconditioning activated both the Akt and ERK1/2 arm of the reperfusion injury salvage kinase (RISK) pathway. To further confirm this mechanism, the PI3K signaling inhibitor LY294002 and ERK1/2 signaling inhibitor PD98059 were administered in vivo. The cardioprotective and anti-apoptotic effects of Peoniflorin preconditioning were diminished but not abolished by pretreatment with LY294002 or PD98059. Taken together, these results indicate that Peoniflorin preconditioning protects the myocardial against I/R injury and inhibits myocardial apoptosis via the activation of the RISK pathway, highlighting the potential therapeutic effects of Peoniflorin on reducing myocardial I/R injury.

Brunel, Jeremie; Mongin, Olivier; Jutand, Anny; Ledoux, Isabelle; Zyss, Joseph; Blanchard-Desce, Mireille published the artcile< Propeller-Shaped Octupolar Molecules Derived from Triphenylbenzene for Nonlinear Optics: Synthesis and Optical Studies>, Product Details of C19H34O2, the main research area is propeller shaped octupolar mol triphenylbenzene derivative; nonlinear optical material synthesis property.

Nanoscale propeller-shaped conjugated mols. based on a central triphenylbenzene core bearing three oligomeric phenylene-vinylene branches having either electron-donating or electron-withdrawing peripheral groups were synthesized. These octupolar derivatives show definite solvatochromic behavior (in absorption and even more in emission), which reveals a multidimensional intramol. charge transfer (MDICT) taking place between the center and the periphery of the mols. Correlations between the solvatochromism magnitude and the nonlinear responses (1st-order hyperpolarizabilities β) of such derivatives were established. Accordingly, boosting of the MDICT phenomenon (by elongation of the branches and benefit from appropriate peripheral groups) allowed achievement of very high hyperpolarizabilities while maintaining wide transparency in the visible region (up to ||β|| = 810 × 10-30 esu for λmax = 377 nm).
