Chemistry 2024:e202303483. [PMID: 38656538 DOI: 10.1002/chem.202303483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 04/10/2024] [Accepted: 04/24/2024] [Indexed: 04/26/2024]
Abstract
Clathrate hydrates are among the most intensively studied H-bond inclusion compounds. Despite the broad definition for this class of compounds, their meaning commonly refers to closed polyhedral nanocages that encapsulate small guest molecules. On the other hand, larger solutes enforce another type of encapsulation because of the solute size effect. Herein, we report a series of structures containing various molecules encapsulated by intercalated water layers constructed of polycyclic moieties of L4(4)8(8) topology. We parametrized the corrugation of individual layers and characterized interactions governing their formation. We suggested that these could be categorized as two-dimensional clathrates based on the character of intra-layer interactions and the effects observed between entrapped molecules and water-based intercalators.

Abstract
Diversity-Oriented Synthesis (DOS) represents a strategy to obtain molecule libraries with diverse structural features starting from one common compound in limited steps of synthesis. During the last two decades, DOS has become an unmissable strategy in organic synthesis and is fully integrated in various drug discovery processes. On the other hand, natural products with multiple relevant pharmacological properties have been extensively investigated as scaffolds for ligand-based drug design. In this article, we report the amino dimethoxyacetophenones that can be easily synthesized and scaled up from the commercially available 3,5-dimethoxyaniline as valuable starting blocks for the DOS of natural product analogs. More focus is placed on the synthesis of analogs of flavones, coumarins, azocanes, chalcones, and aurones, which are frequently studied as lead compounds in drug discovery.

Translational and pharmacological principles of hyperthermic intraperitoneal chemotherapy for ovarian cancer. Best Pract Res Clin Obstet Gynaecol 2021; 78:86-102.

Abstract
The long-term survival of advanced-stage ovarian cancer patients remains poor, despite extensive cytoreductive surgery, chemotherapy, and the recent addition of poly (ADP-ribose) polymerase inhibitors (PARPi). Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown survival benefit by specifically targeting peritoneal metastases, the primary site of disease recurrence. Different aspects of how HIPEC exerts its effect remain poorly understood. Improved understanding of the effects of hyperthermia on ovarian cancer cells, the synergy of hyperthermia with intraperitoneal chemotherapy, and the pharmacological and pharmacokinetic properties of intraperitoneally administered cisplatin may help identify ways to optimize the efficacy of HIPEC. This review provides an overview of these translational and pharmacological principles of HIPEC and aims to expose knowledge gaps that may direct further research to optimize the HIPEC procedure and ultimately improve survival for women with advanced ovarian cancer.

Pharmaceuticals (Basel) 2020; 13:ph13120433. [PMID: 33260497 PMCID: PMC7768359 DOI: 10.3390/ph13120433] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 11/24/2020] [Accepted: 11/25/2020] [Indexed: 12/01/2022] Open
Abstract
A series of eight novel platinum(II) complexes were synthesized by the reaction of the appropriate 1-methylnitropyrazole derivatives with K2PtCl4 and characterized by elemental analysis, ESI MS spectrometry, 1H NMR, 195Pt NMR, IR and far IR spectroscopy. Thermal isomerization of cis-dichloridobis(1-methyl-4-nitropyrazole)platinum(II) 1 to trans-dichloridobis(1-methyl-4-nitropyrazole)platinum(II) 2 has been presented, and the structure of the compound 2 has been confirmed by X-ray diffraction method. Cytotoxicity of the investigated compounds was examined in vitro on three human cancer cell lines (MCF-7 breast, ES-2 ovarian and A-549 lung adenocarcinomas) and their logP was measured using a shake-flask method. The trans complex 2 showed better antiproliferative activity than cisplatin for all the tested cancer cell lines. Additionally, trans-dichloridobis(1-methyl-5-nitropyrazole)platinum(II) 4 has featured a lower IC50 value than reference cisplatin against MCF-7 cell line. To gain additional information that may facilitate the explanation of the mode of action of tested compounds cellular platinum uptake, stability in L-glutathione solution, influence on cell cycle progression of HL-60 cells and ability to apoptosis induction were determined for compounds 1 and 2.
