Cancer is one of the major causes of death worldwide, and breast cancer is the most prevalent and deadly type among women. Despite the side effects and the phenomena of chemoresistance associated with the drugs involved, chemotherapy remains the main therapeutic strategy to combat and control breast cancer. Therefore, several new classes of compounds against breast cancer have been explored, in an effort to identify new drug candidates with alternative mechanisms of action. The principal results of such exploration, focusing on caged xanthones, thiosemicarbazones and photosensitizers, are presented in this review, along with the main aspects of the drug discovery process against breast cancer. More specifically, the design, structure-activity relationship investigations and anti-breast cancer properties of these three classes are described and discussed in this work.

Chikungunya virus (CHIKV) is the causative agent of chikungunya fever, a disease that can result in disability. Until now, there is no antiviral treatment against CHIKV, demonstrating that there is a need for development of new drugs. Studies have shown that thiosemicarbazones and their metal complexes possess biological activities, and their synthesis is simple, clean, versatile, and results in high yields. Here, we evaluated the mechanism of action (MOA) of a cobalt(III) thiosemicarbazone complex named [CoIII(L1)2]Cl based on its in vitro potent antiviral activity against CHIKV previously evaluated (80% of inhibition on replication). Furthermore, the complex has no toxicity in healthy cells, as confirmed by infecting BHK-21 cells with CHIKV-nanoluciferase in the presence of the compound, showing that [CoIII(L1)2]Cl inhibited CHIKV infection with the selective index of 3.26. [CoIII(L1)2]Cl presented a post-entry effect on viral replication, emphasized by the strong interaction of [CoIII(L1)2]Cl with CHIKV non-structural protein 4 (nsP4) in the microscale thermophoresis assay, suggesting a potential mode of action of this compound against CHIKV. Moreover, in silico analyses by molecular docking demonstrated potential interaction of [CoIII(L1)2]Cl with nsP4 through hydrogen bonds, hydrophobic and electrostatic interactions. The evaluation of ADME-Tox properties showed that [CoIII(L1)2]Cl presents appropriate lipophilicity, good human intestinal absorption, and has no toxicological effect as irritant, mutagenic, reproductive, and tumorigenic side effects.

In this study, synthesis, characterization, DFT and evaluation of the theoretical antibacterial activity through molecular docking of two different Nickel(II) complexes based on 2‐acetylpyridine‐N(4)‐R‐thiosemicarbazone are described. The ligand where R=ethyl is named L¹ and its complex [NiII(L¹)2] (Complex 1) while, for the second complex, R is phenyl (L²) resulting in a novel [NiII(L²)2] complex (Complex 2). The compounds were characterized by infrared and ultraviolet spectroscopy and elemental analysis. The molecular structure of 1 was determined by single‐crystal X‐ray diffraction. The complex crystallizes in monoclinic crystal system, adopting a distorted octahedral geometry and the crystal lattice is stabilized by H⋅⋅⋅H, C⋅⋅⋅H/H⋅⋅⋅C, N⋅⋅⋅H/H⋅⋅⋅N and S⋅⋅⋅H/H⋅⋅⋅S interactions (Hirshfeld Surfaces). The results of density functional theory provided information about molecular structures, molecular frontier orbital and theorical IR and the UV‐Vis spectra of 1 and 2. The molecular docking and in silico analysis of pharmacokinetic parameters of the compounds showed promising results.

Journal of Inorganic Biochemistry

In the present work, the synthesis, characterization, antifungal activity, molecular docking study and in silico approach of five thiosemicarbazone derivatives and their corresponding zinc(II) complexes are described. The compounds were characterized by elemental analysis, IR, UV–Vis and NMR spectroscopic measurements, molar conductivity measurements, emission spectra, high-resolution mass spectrometry and X ray study. The antifungal activity of the free ligands and synthesized compounds was preliminarily evaluated against Candida albicans (ATCC 90028), Candida tropicalis (ATCC 13803) and Candida glabrata (ATCC 2001), by the minimum inhibitory concentration (MIC) assay. Two complexes, 4 (MIC = 3.18 to 6.37 μM) and 5 (MIC = 25.95 μM for all) showed promising results, being highly active against all strains evaluated. The X-ray analyses shown that the complex 2 crystallizes in the centrosymmetric space group P21/c of the monoclinic system and the coordination sphere around zinc(II) atom is better described as slightly distorted octahedral. The Hirshfeld surface (HS) analysis showed that non-classical H···H and C···H/H···C contacts contribute with 65.9% while the S···H and N···H (21%) and Cl···H and O···H interactions (12%) complete the HS area. The molecular docking results, performed against CYP51 enzyme (sterol 14α-demethylase) of C. albicans and C. glabrata shows that the complexes 4 (ΔG = −10.75 and − 12.90 kcal/ mol) and 5 (ΔG = −11.12 and − 14.53 kcal/ mol) showed the highest binding free energies of all compounds. The ADME-Tox (absorption, distribution, metabolism, excretion and toxicity) in silico parameters evaluated showed promising results for all compounds.

... Related compounds, such as p-acetamidobenzaldehyde thiosemicarbazone (amithionoze©) already at the second World War (in Africa and South America), showed bacteriostatic efficiency on Mycobacterium tuberculosis in combination with isoniazid 8 , and in general, those TSCN with better lipophilicity and available binding sites showed the best performance ( Figure 1a, binging sites highlighted in yellow) 5 . Thereafter, this TSCN's effectiveness has been improved in some cases with copper metalation (mononuclear complexes; Figure 1b; X:Cl and dinuclear compounds; Figure 1c; Y = SO 4 ) 9 , achieving even synthetic fibers with excellent growth inhibition by grafting antibacterial copper TSCNs onto cellulose (Figure 1b; X:OH) 10 . ...

Furthermore, if changes to the inorganic component are required, it often demands an entirely new fabrication process, adding further complexity and potential inefficiencies to the overall procedure. ...
