Small Molecules Blocking the Assembly of TCAB1 and Telomerase Complexes: Lead Discovery and Biological Activity.

The vast majority of tumor cells maintain the length of the telomeres through a telomerase-dependent maintenance mechanism, allowing for unlimited proliferation. TCAB1 is indispensable for the correct assembly of telomerase complexes and the delivery of telomerase to the telomere. Therefore, this study aimed to explore small molecules capable of interfering with the assembly of TCAB1 and the telomerase complex as novel efficient telomerase inhibitors.

Directly Suppressing MYC Function with Novel Alkynyl-Substituted Phenylpyrazole Derivatives that Induce Protein Degradation and Perturb MYC/MAX Interaction.

Despite being a highly sought-after therapeutic target for human malignancies, myelocytomatosis viral oncogene homologue (MYC) has been considered intractable due to its intrinsically disordered nature, making the discovery of in vivo effective inhibitors that directly block its function challenging. Herein, we report structurally novel alkynyl-substituted phenylpyrazole derivatives directly perturbing MYC function. Among them, compound exhibited superior antiproliferative activities to those of MYCi975 against multiple malignant cell lines.

Ruptured liquid metal microcapsules enabling hybridized silver nanowire networks towards high-performance deformable transparent conductors.

Extensive studies have been carried out on silver nanowires (AgNWs) in view of their impressive conductivity and highly flexible one-dimensional structure. They are seen as a promising choice for producing deformable transparent conductors. Nonetheless, the widespread adoption of AgNW-based transparent conductors is hindered by critical challenges represented by the significant contact resistance at the nanowire junctions and inadequate interfacial adhesion between the nanowires and the substrate.

Cyclin-Dependent kinase 9 (CDK9) inhibitor Atuveciclib ameliorates Imiquimod-Induced Psoriasis-Like dermatitis in mice by inhibiting various inflammation factors via STAT3 signaling pathway.

Psoriasis is a chronic, autoimmune skin disease characterized by the deregulated secretion of inflammatory factors in multiple organs. The aberrant activation of signal transducer and activator of transcription 3 (STAT3) signaling pathway mediated by cyclin-dependent kinase 9 (CDK9) is vital for the pathology of psoriasis, leading to the accumulation of inflammatory factors and the progression of skin damage. In this study, we explored the effect of CDK9 inhibition on attenuating the secretion of inflammatory factors and alleviating skin damage in psoriasis models both in vitro and in vivo.

Targeted liposomes for macrophages-mediated pulmonary fibrosis therapy.

Pulmonary fibrosis (PF) is a horrible lung disease that causes pulmonary ventilation dysfunction and respiratory failure, severely impacting sufferers' physical and mental health. Existing drugs can only partially control the condition and are prone to toxic side effects. Anti-inflammatory treatment is the committed step to alleviate PF.
