It has been well accumulated that G-quadruplex (G4-DNA) has great anticancer relevance, and various heterocyclic moieties have been synthesized and examined as potent G4-DNA binders with promising anticancer activity. Here, we have synthesized a series of naphthalimide-triazole-coumarin conjugates by substituting various amines and further examine their anticancer activity against 60 human cancer cell lines at 10 μM. One and five dose concentration results reveal low values of MG-MID GI for compounds including (3.

The spontaneous aggregation of amyloid-β (Aβ) leads to neuronal cell death in the brain and causes the development of Alzheimer's disease (AD). The efficient detection of the aggregation state of Aβ holds significant promise for the early diagnosis and subsequent treatment of this neurodegenerative disorder. Currently, most of the fluorescent probes used for the detection of Aβ fibrils share similar recognition moieties, such as the ,-dimethylamino group, ,-diethylamino group, and piperidyl group.

Repairing large bone defects remains a significant clinical challenge. Stem cell is of great importance in bone regeneration, and periosteum is rich in periosteal stem cell, which has a great influence on repairing bone defects. Bioengineered periosteum with excellent biocompatibility and stem cell homing capabilities to promote bone regeneration is of great clinical significance.

Introduction: Hypericin (HP), a natural photosensitizer, has demonstrated great efficacy in photodynamic therapy (PDT) for cancer treatment. In addition to the induction of apoptosis and necrosis through reactive oxygen species (ROS) generation, the therapeutic mechanisms and targets of PDT-HP remain unknown.
Objectives: To investigate the direct targets and mechanisms of action of photoactivated hypericin in the inhibition of triple-negative breast cancer (TNBC).

Acylaminoacyl-peptide hydrolase (APEH), a serine peptidase that belongs to the prolyl oligopeptidase (POP) family, catalyzes removal of N-terminal acetylated amino acid residues from peptides. As a key regulator of protein N-terminal acetylation, APEH was involved in many important physiological processes while its aberrant expression was correlated with progression of various diseases such as inflammation, diabetics, Alzheimer's disease (AD), and cancers. However, while emerging attention has been attracted in APEH-related disease diagnosis and drug discovery, the mechanisms behind APEH and related disease progression are still unclear; thus, further investigating the physiological role and function of APEH is of great importance.
