Highly phosphorescent N^C^N platinum(II)-peptide nucleic acid conjugates: synthesis, photophysical studies and hybridization behaviour.

The synthesis of novel highly phosphorescent N^C^N tridentate platinum(II)-complex-peptide nucleic acid (PNA) bioconjugates was accomplished through the solid-phase approach. Melting temperature measurements and circular dichroism spectroscopy studies demonstrated that these conjugates maintain the PNA ability to recognize complementary ssDNA and ssRNA, though the length of the spacer between the metal center and the PNA sequence affects their hybridization properties. Noteworthy, the conjugation of PNA to this family of Pt(II) complexes significantly enhanced the luminescent features of the organometallic moiety, leading to increased quantum yields (82.

Background And Objective: Pulmonary carcinoids (PCs) represent a rare subset of neuroendocrine tumors (NETs) within the respiratory tract that exhibit unique characteristics and clinical behaviors. These tumors are currently staged according to the tumor-nodules-metastases (TNM) classification of non-small cell lung cancer (NSCLC), which brings their reliability into question. The aim of this study was to assess reliability of the current TNM staging of PCs and explore other relevant prognostic factors of patient outcomes.

Emerging insights into , and mutations: implications for immunotherapy in patients with advanced non-small cell lung cancer.

Immune checkpoint inhibitors (ICIs) have become an established treatment option for patients with advanced non-small cell lung cancer (NSCLC). However, the efficacy of single-agent immunotherapy as well as in combination with chemotherapy seems to be dependent on the presence of molecular abnormalities in some genes-serine/threonine kinase 11 (), Kelch-like ECH-associated protein 1 () and Kirsten rat sarcoma viral oncogene homolog () among them. The gene is a critical regulator of the cellular response to oxidative stress and electrophilic stress, thus playing a pivotal role in maintaining cellular homeostasis.

Time-resolved and theoretical analysis of Mo-carbene transformations in metathesis of ethylene with 2-butene.

Although supported Mo-containing catalysts have been extensively investigated in the metathesis of ethylene with 2-butene to propene, the mechanisms of the formation and transformation of catalytically active Mo-carbenes in the course of the reaction are still not fully understood. The difficulties arise because only a tiny fraction of MoO species can form Mo-carbenes , making the detection of the latter by spectroscopic means very unlikely. Herein, purposefully designed steady-state and transient experiments including their kinetic evaluation and density functional theory calculations enabled us to elucidate mechanistic and kinetic details of the above reaction-induced processes in the metathesis reaction over a Mo/P/SiO catalyst at 50 °C.
