The reaction of nickel(II) thio-cyanate with an excess of pyridazine leads to single crystals of the title compound, [Ni(NCS)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2). The Ni(II) cations are coordinated by two terminal N-bonded thio-cyanate anions (trans) and four pyridazine ligands in a slightly distorted octa-hedral geometry. The discrete complexes are arranged into layers parallel to the ab plane which are separated by additional non-coordinated pyridazine ligands.

As a result of drug resistance, many antimicrobial medicines become ineffective, making the infections more difficult to treat. Therefore, there is a need to develop new compounds with antibacterial activity. This role may be played, for example, by metal complexes with carboxylic acids.

Nanoparticulate drug combination inhibits DNA damage repair and PD-L1 expression in BRCA-mutant and wild type triple-negative breast cancer.

J Control Release

January 2025

Advanced Pharmaceutics and Drug Delivery Laboratory, Leslie Dan Faculty of Pharmacy, University of Toronto, 144 College Street, Toronto M5S 3M2, Ontario, Canada. Electronic address:

Article Synopsis
  • Metastatic breast cancer has a high mortality rate and is hard to treat, especially in triple-negative breast cancer (TNBC) due to factors like DNA repair and immunosuppression.
  • PARP inhibitors like olaparib can help, but problems like drug resistance and increased PD-L1 can limit their effectiveness.
  • The study tested a new treatment using specialized polymer-lipid nanoparticles carrying doxorubicin to target TNBC, showing better results in reducing tumor growth and metastasis compared to olaparib.

Regioselective Copper(I)-Catalyzed Direct C(3)-H (Hetero)arylation of 6-(Hetero)arylated 1,2,4-Triazolo[4,3-]pyridazines: Ligand-Free Approach.

J Org Chem

December 2024

Laboratory of Physico-Chemistry of Materials and Electrolytes for Energy (PCM2E), Faculty of Sciences and Technologies, University of Tours, Tours 37200, France.

The first efficient Cu(I) catalyzed regioselective C3-(hetero)arylation of 6-(hetero)arylated 1,2,4-triazolo[4,3-]pyridazines has been developed to streamline the synthesis of pharmaceutically important 3,6-diarylated 1,2,4-triazolo[4,3-]pyridazines. This direct (hetero)arylation is compatible with a range of aryl iodides and tolerates a variety of functional groups (23 examples). A series of new 3,6-diarylated 1,2,4-triazolo[4,3-]pyridazines were synthesized with good to excellent yields (up to 98%).

Design, Synthesis, and Activity of a Novel Series of Pyridazine-Based ALK5 Inhibitors.

ACS Med Chem Lett

November 2024

Chiesi Farmaceutici S.p.A., Centro Ricerche, Largo Belloli 11/a, 43122 Parma, Italy.

Article Synopsis
  • - Researchers developed new ALK5 inhibitors aimed at treating diseases like cancer and fibrosis, focusing on a specific chemical structure called a 4,6-disubstituted pyridazine core.
  • - They used a method called "scaffold-hopping" to explore different chemical frameworks and found a particularly effective compound that was enhanced for inhalation, reducing the risk of side effects.
  • - The optimized ALK5 inhibitors demonstrated improved effectiveness and properties for lung retention, suggesting they could be good candidates for creating new inhaled treatment options.

Photoinduced Copper-Catalyzed Cross-Coupling of Acylsilanes with Heteroarenes via Bimetallic Relay.

Adv Sci (Weinh)

December 2024

The transition metal-catalyzed direct coupling reactions involving electron-rich Fischer carbene species are largely underdeveloped and remain a big challenge. Here, a direct coupling reaction of azoles and azine N-oxides is reported with Fischer copper carbene species bearing an α-siloxy group i, which can be in situ generated from acylsilanes catalytically under photoirradiation and redox-neutral conditions. This coupling reaction between electron-rich α-siloxy Fischer Cu-carbene species with hard carbanion nucleophiles may undergo a bimetallic relay process, which is confirmed by the kinetic analysis and in situ NMR analysis.
