With the aim to incorporate pharmacophore motifs into the Ru(II)-polypyridyl framework, compounds [Ru(II)(1,10-phenantroline)2(2-(2-pyridyl)benzo[b]thiophene)](CF3SO3)2 (1) and [Ru(II)(1,10-phenantroline)2(2-(2-pyridyl)benzimidazole)](CF3SO3)2 (2) were prepared, characterized and tested for their antitumor potential. The solid-state structure of the compounds was confirmed by single-crystal X-ray diffraction analysis. The solution behavior of both complexes was investigated, namely their solubility, stability, and lipophilicity in physiological mimetic conditions, as well as an eventual uptake by passive diffusion. In vitro anticancer activity of the complexes on ovarian and different colon cancer cells and apoptosis induction by the complexes were studied. A slow transformation process was observed for complex 1 in aqueous solution when exposed to sunlight, while complex 2 undergoes deprotonation (pKa = 7.59). The lipophilicity of this latter complex depends strongly on the pH and ionic strength. In contrast, 1 is rather hydrophilic under various conditions. Complex 1 was highly cytotoxic on Colo-205 human colon (IC50 = 7.87 μM) and A2780 ovarian (IC50 = 2.2 μM) adenocarcinoma cell lines, while 2 displayed moderate anticancer activity (30.9 μM and 18.0 μM, respectively). The complexes induced late apoptosis and necrosis. Only a weak binding of the complexes to human serum albumin, the main transport protein in blood serum, was found. However, a more significant binding to calf thymus DNA was observed in UV-visible titrations and fluorometric dye displacement studies. Detailed analysis of fluorescence lifetime data collected for the latter systems reveals not only the partial intercalation of the complexes, but goes beyond the usual simplified interpretations.
Physician burnout is a major problem in the United States. Small studies suggest scribes can improve clinician satisfaction, but scribe programs have not been evaluated using separate control groups or structured measures of electronic health record (EHR) use.
We conducted a pre-post, non-randomized controlled evaluation of a remote scribe pilot program introduced in September 2019 in an academic primary care practice. Scribes were paired with physicians via an audio-only cellphone connection to hear and document in real-time. Physician wellness was measured with the 10-item Mini-Z and 16-item Professional Fulfillment Index. EHR use was measured using vendor-derived platforms that provide routine EHR-related data.
37 of 38 scribe users (97.4%) and 68 of 160 potential control physicians (42.5%) completed both pre and post intervention questionnaires. Compared with controls, scribe users had improvements in Mini-Z wellness metrics including Joyful Workplace (mean improvement 2.83, 95%CI 0.60, 5.06) and a single-item dichotomized burnout measure (OR 0.15, 95%CI 0.03, 0.71). There were significant reductions among scribe users compared to controls in total EHR time per 8 scheduled hours (-1.14h, 95%CI -1.55, -0.72), and an increase in the percentage of orders with team contribution (10.4%, 95%CI 5.2, 15.6). These findings remained significant in adjusted analyses.
A remote scribe program was associated with improvements in physician wellness and reduced EHR use. Healthcare organizations can consider scribe programs to help improve wellness among their physician workforce.

To explore the mechanism of steroidogenic acute regulatory (StAR)-related lipid transfer domain containing 3 (STARD3) in breast cancer (BC).
We analysed the differential mRNA expressions of BC using ER
and ER
BC expression profiles from the cancer genome atlas (TCGA). Expression and correlation between salient genes was visualized using microarray volcano plots and a protein-protein interaction (PPI) network map. Survival analyses were performed to identify the potential for STARD3 to serve as a prognostic biomarker. The expression of STARD3 was examined by immunohistochemistry (IHC). The effects of STARD3 on apoptosis and proliferation of BC (MCF-7) cell line were deduced by flow cytometry, CCK8, and western blot (WB).
STARD3 was the most differentially expressed gene (DEG). Patients in the STARD3 high expression group had significantly lower survival than those in the low expression group. The expression of STARD3 was significantly higher in BC tissues than controls. Inhibiting STARD3 expression significantly increased apoptosis, decreased proliferation, activated PI3K/AKT/mTOR pathway CONCLUSION Inhibiting the expression of STARD3 induced apoptosis via the inactivation of PI3K/AKT/mTOR pathway on BC inhibits tumour growth, which can be an effective therapeutic strategy.

Hence, in this study, a new series of novel coumarin-4-yl-1,2,3-triazol-4-yl-methyl-thiazolidine-2,4-diones (TZD1-TZD18) were synthesized via copper (I)-catalyzed azide-alkyne cycloaddition "Click Chemistry". The synthesized compounds were evaluated for their glucose uptake assay and in vitro cytotoxicity against HEK-293 (human embryonic kidney) cells which were compared with the standard drug Pioglitazone. Further, molecular docking analysis of these compounds was carried out to explain the in vitro results with PPARγ (PDB ID 3CS8) and to better understand the bonding interactions with the target protein. The outcomes of in vitro assessment, molecular docking, and pharmacokinetics of the title compounds were revealed to be highly correlated. Interestingly, the compounds TZD4, TZD10, TZD14 and TZD16 were most efficient in lowering the blood glucose level compared with standard drug.Ras protein has been considered a fascinating target for anticancer therapy because its malfunction is closely related to cancer. However, Ras has been considered undruggable because of the failure to regulate its malfunction by controlling the Ras activation mechanism. Recently, Lumakras targeting the G12C mutation was approved, and therapeutic interest in Ras for anticancer therapy has been rejuvenated. Here, we present a series of compounds that inhibit Ras via a unique mechanism of action that exploits the relationship between the Wnt/β-catenin pathway and Ras. KYA1797K (1) binds to axin to stabilize the β-catenin destruction complex that causes the phosphorylation and subsequent degradation of Ras, similar to canonical β-catenin regulation. Based on the chemical structure of 1, we performed a structural optimization and identified 3-(2-hydroxyethyl)-5-((6-(4-nitrophenyl)pyridin-2-yl)methylene)thiazolidine-2,4-dione (13d) as the most potent compound. 13d displayed antitumor effects in a colorectal cancer model with enhanced inhibition activity on Ras. The results of this study suggest that the further development of 13d could contribute to the development of Ras inhibitors with novel mechanisms of action.Colorectal cancer is a type of cancer encountered worldwide and ranks third among all cancer types in terms of incidence. Polyphenols have been shown to have a wide range of biological functions, including a significant impact on cancer start, development, and promotion through regulating many signaling pathways. The aim of this study was to investigate the anticancer effects of isoeugenol based compounds 1, 2 on HT29 colorectal cancer cell line in vitro. MTT test and scratch assay were carried out to determine the effect of these compounds on HT29 cell proliferation and migration respectively. In addition, mRNA expression levels of apoptosis and metastasis-related genes (p53, Bcl2, Bax, Caspase 3, Caspase7, Caspase8, Caspase9, HIF1-α, VEGF, MMP-2, MMP-9) were examined by quantitative real-time PCR. selleckchem The results indicated that 1 and 2 inhibited HT29 cell proliferation and induced apoptosis by increasing the Bax/Bcl2 ratio and Caspase-9 and Caspase-3 mRNA expression. In conclusion, the results of this study showed that the treatment of these compounds significantly suppressed the mRNA expressions of metastasis-related genes such as Matrix Metalloproteinase-2, Matrix Metalloproteinase-9, Vascular Endothelial Growth Factor and Hypoxia‑Inducible Factor 1α.Natural products have been an important database for anti-cancer drug development. However, low water solubility and poor biocompatibility limit the efficacy of natural products. Carbon dots (CDs), as an emerging 0D material, have unique properties in bioimaging, water solubility and biocompatibility. Here, we prepared three pentacyclic triterpenoids (PTs) included glycyrrhetinic acid (GA), ursolic acid (UA) and oleanolic acid (OA), which have anticancer activity but poor water solubility, as raw materials into CDs to improve disadvantages. Our data indicated that the active surface groups of all three CDs were largely preserved and were able to excite green fluorescence. Their carboxyl edges not only exhibited excellent water solubility, but also specifically targeted tumor cell mitochondria due to high sensitivity to ROS-induced damage and high internal oxidative stress. In cancer cells, the PT-CDs induced cell death through three pathways (apoptosis, ferroptosis, and autophagy), which is essentially the same way their raw materials induce death, but the effect was much stronger than raw materials. Notably, functionalized PT-CDs also exhibited extremely low toxicity. In summary, PT-CDs not only have improved water solubility and biocompatibility, but also retain the structure of their raw materials well and exert better efficacy, which provides new ideas for the development of anti-cancer natural product drugs.Bruton's tyrosine kinase (BTK) is a promising drug target for the treatment of B-cell related malignancies. Irreversible inhibition of BTK by a covalent inhibitor has been proved to be a clinically effective therapy. However, most irreversible BTK inhibitors also inhibit other kinases including JAK3 and EGFR, leading to some adverse events. Herein, we reported the structure-based design and optimization of a series of irreversible BTK inhibitors bearing the 6-amino-1,3,5-triazine scaffold. Most of the synthesized compounds demonstrated considerable BTK inhibition and improved anti-proliferative activity against Raji and Ramos cells. Among them, compound C11 exhibited potent BTK inhibition (BTK IC50 = 17.0 nM) and a desirable selectivity profile especially over EGFR. Moreover, C11 effectively blocked activation of BTK and downstream signaling, arrested the cell cycle in G0/G1 phase and induced apoptosis in Raji cells. Its irreversible binding mode was further investigated by both molecular modeling and a washout experiment.
