Incorporation of a rigid 1,3-diketone-containing fragment led to significantly improved AXL inhibitory activity: design, synthesis, and SAR of the anilinopyrimidine AXL inhibitors.

Overexpressed AXL kinase is involved in various human malignancies, which incurs tumor progression, poor prognosis, and drug resistance. Suppression of the aberrant AXL axis with genetic tools or small-molecule inhibitors has achieved valid antitumor efficacies in both preclinical studies and clinical antitumor campaigns. Herein we will report the design, synthesis, and structure-activity relationship (SAR) exploration of a series of anilinopyrimidine type II AXL inhibitors.

Ultrathin, Friendly Environmental, and Flexible CsPb(Cl/Br)-Silica Composite Film for Blue-Light-Emitting Diodes.

Due to intrinsic defects in blue-light-emitting perovskite materials, the charge carriers are prone to being trapped by the trap states. Therefore, the preparation of efficient blue-light-emitting perovskite materials remains a significant challenge. Herein, CsPb(Cl/Br) nanocrystal (NCs)@SiO structures were fabricated through hydrolyzing (3-aminopropyl)-triethoxysilane (APTS).

Development and Validation of an Interpretable Machine Learning Model to Predict Major Adverse Cardiovascular Events After Noncardiac Surgery in Geriatric Patients: a Prospective Study.

Background: Major adverse cardiovascular events (MACEs) within 30 days following noncardiac surgery are prognostically relevant. Accurate prediction of risk and modifiable risk factors for postoperative MACEs is critical for surgical planning and patient outcomes. We aimed to develop and validate an accurate and easy-to-use machine learning model for predicting postoperative MACEs in geriatric patients undergoing noncardiac surgery.

Enhanced Synthesis of Volatile Compounds by UV-B Irradiation in Leaves.

Volatile compounds have a deep influence on the quality and application of the medicinal herb ; however, little is known about the effect of UV-B radiation on volatile metabolites. We herein investigated the effects of UV-B exposure on the volatile compounds and transcriptome of to assess the potential for improving its quality and medicinal characteristics. Out of 733 volatiles obtained, a total of 133 differentially expressed metabolites (DEMs) were identified by metabolome analysis.

Multidimensional Characterization of the Physiological State of Hematococcuspluvialis Using Scanning Structured Illumination Super-Resolution Microscopy.

(HP) is a freshwater alga known for its ability to accumulate the potent antioxidant astaxanthin, which has extensive applications in aquaculture, pharmaceuticals, and cosmetics. Astaxanthin rapidly accumulates under unfavorable environmental conditions. However, the mechanisms of astaxanthin accumulation under various stress conditions remain unclear.
