abstract = {<jats:p>Background/Objectives: Dithiocarbazates (DTCs) and their metal complexes have been studied regarding their property as anticancer activities. In this work, using S-benzyl-5-hydroxy-3-methyl-5-phenyl-4,5-dihydro-1H-pirazol-1-carbodithionate (H2bdtc), we prepared [ReO(bdtc)(Hbdtc)] and [[99mTc]TcO(bdtc)(Hbdtc)] complexes for tumor uptake and animal biodistribution studies. Methods: Re complex was prepared by a reaction of H2bdtc and (NBu4)[ReOCl4], the final product was characterized by IR, 1H NMR, CHN, and MS-ESI. 99mTc complex was prepared by the reaction of H2bdtc and [[99mTc]TcO4− and analyzed by planar and HPLC radiochromatography, and the stability was evaluated against amino acids and plasma. Biodistribution was performed in C57B/6 mice with B16F10 and TM1M implanted tumor. Results: Re is asymmetric coordinated by two dithiocarbazate ligands, one with O,N,S chelation, and the other with N,S chelation; [[99mTc]TcO(bdtc)(Hbdtc)] was prepared with a radiochemical yield of around 93%. The radioactive complex is hydrophobic (LogP = 1.03), stable for 6 h in PBS and L-histidine solution; stable for 1 h in plasma, but unstable in the presence of L-cysteine. Ex vivo biodistribution demonstrated that the compound has a fast and persistent (until 2 h) uptake by the spleen (55.46%), and tumor B16F10 and TM1M uptake is lower than 1%. In vivo SPECT/CT imaging confirmed ex vivo biodistribution, except by heterogenous TM1M accumulation but not in the B16-F10 lineage. Conclusions: H2bdtc proved to be an interesting chelator for rhenium or [99mTc]technetium. The right spleen uptake opened the opportunity to deepen the study of the molecule in this tissue and justifies future studies to identify the reason of heterogenous uptake in TM1M tumor uptake.</jats:p>},

abstract = {<jats:title>Abstract</jats:title><jats:p>Neglected tropical viral diseases are a burden to social and economic welfare being responsible for higher pathogen‐related mortality rates and chronic debilitating patient conditions. Climatic changes have widened up the infectibility ratio of such diseases, with autochthonous transmission in formerly temperate‐to‐cold environments. The slow‐paced development of potential vaccines followed by the inexistence of antiviral drugs for such diseases considerably worsens the situation. Coordination compounds are a class of molecules that have been extensively explored as antiviral drugs for viruses such as poliovirus, HIV and, more recently, SARS‐CoV‐2, figuring as potential molecules to be explored and capitalized as antivirals against neglected viral strains. In this review the current efforts from the inorganic medicinal chemistry to address viral neglected tropical diseases, with emphasis to coordination compounds, is presented. Since many of neglected viruses are also arthropod‐borne viruses, relying on a vector for transmission, coordination entities able to mitigate vectors are also presented as a parallel strategy to prevent and control such diseases.</jats:p>},

abstract = {<jats:title>Abstract</jats:title><jats:p>Breast cancer remains a pressing public health issue primarily affecting women. Recent research has spotlighted bioactive peptides derived from laminin-111, implicated in breast tumor development. Remarkably, the sequences IKVAV, YIGSR, and KAFDITYVRLKF from the α1, β1, and γ1 chains, respectively, have garnered significant attention. This study aims to assess the potential of these radiolabeled peptides as targeting agents for breast cancer. The three peptides were synthesized using the Fmoc strategy, purified via reversed-phase high-performance liquid chromatography (RP-HPLC), and characterized through mass spectrometry. Iodine-131 (<jats:sup>131</jats:sup>I) radiolabeling was performed using the chloramine T method, exhibiting high radiochemical yield and stability for [<jats:sup>131</jats:sup>I]I-YIKVAV and [<jats:sup>131</jats:sup>I]I-YIGSR. Conversely, [<jats:sup>131</jats:sup>I]I-KAFDITYVRLKF demonstrated low radiochemical yield and stability and was excluded from the biological studies. The lipophilicity of the compounds ranged from − 2.12 to − 1.10. Serum protein binding assay for [<jats:sup>131</jats:sup>I]I-YIKVAV and [<jats:sup>131</jats:sup>I]I-YIGSR reached ≅ 48% and ≅ 25%, respectively. Affinity for breast cancer cells was evaluated using MDA-MB-231 and MCF-7 tumor cell lines, indicating the affinity of the radiopeptides with these tumor cells. Ex vivo biodistribution profiles of the radiopeptides were assessed in the MDA-MB-231 breast tumor animal model, revealing tumor tissue accumulation, supported by a high tumor-to-contralateral muscle ratio and autoradiography. These results signify the effective penetration of YIKVAV and YIGSR into tumor tissue. Therefore, the synthesized α1 and β1 peptide fragments exhibit favorable characteristics as potential breast cancer-targeting agents, promising future exploration as radiopharmaceuticals for breast cancer.</jats:p>},

abstract = {<jats:p>Background/Objectives: Triple-negative breast cancer (TNBC) is the most challenging molecular subtype of breast cancer (BC) in clinical practice, associated with a worse prognosis due to limited treatment strategies and its insensitivity to conventional drugs. Zinc is an important trace element for homeostasis, and its Schiff base metal complexes have shown promise in treating advanced tumors. In this study, four new heteroleptic Zn(II) complexes (1–4) with Schiff bases were synthesized, characterized, and evaluated for their activity in BC cells. Methods: Compounds were synthesized, characterized, and their crystal structures were determined. Biological activity was assessed using MTT, clonogenic, scratch wound healing, caspase 3 and 8 activity, qPCR, and chemosensitization assays. Results: The complexes exhibited cytotoxicity against MCF-7 (luminal BC), MDA-MB-453 (HER2-positive BC), and MDA-MB-231 (TNBC) cell lines, with IC50 values ranging from 0.01 to 20 µM. Complex 4 showed reduced cytotoxicity toward non-tumor cell lines. This, complexation with Zn(II) increased the cytotoxicity of the ligands, a trend not observed for complexes 1–3. Due to its favorable profile, complex 4 was selected for further assays, in which it inhibited colony formation and the cell migration of TNBC cells in a dose-dependent manner. Furthermore, this compound induced cell death independently of caspases, decreasing the activity of caspase 8. Interestingly, complex 4 sensitized TBNC cells to doxorubicin and paclitaxel, possibly modulating the epithelial–mesenchymal transition mechanism, as evidenced by increased CDH1 expression. Conclusions: Results suggest the potential of complex 4 in sensitizing aggressive BC cells to chemotherapy, proving to be a promising alternative in cases of therapeutic failure.</jats:p>},

abstract = {<jats:p>The burgeoning field of cancer theranostics has witnessed advancements through the development of targeted molecular agents, particularly peptides. These agents exploit the overexpression or mutations of specific receptors, such as the Epidermal Growth Factor receptor (EGFR) and αVβ3 integrin, which are pivotal in tumor growth, angiogenesis, and metastasis. Despite the extensive research into and promising outcomes associated with antibody-based therapies, peptides offer a compelling alternative due to their smaller size, ease of modification, and rapid bioavailability, factors which potentially enhance tumor penetration and reduce systemic toxicity. However, the application of peptides in clinical settings has challenges. Their lower binding affinity and rapid clearance from the bloodstream compared to antibodies often limit their therapeutic efficacy and diagnostic accuracy. This overview sets the stage for a comprehensive review of the current research landscape as it relates to EGFR- and integrin αVβ3-targeting peptides. We aim to delve into their synthesis, radiolabeling techniques, and preclinical and clinical evaluations, highlighting their potential and limitations in cancer theranostics. This review not only synthesizes the extant literature to outline the advancements in peptide-based agents targeting EGFR and integrin αVβ3 but also identifies critical gaps that could inform future research directions. By addressing these gaps, we contribute to the broader discourse on enhancing the diagnostic precision and therapeutic outcomes of cancer treatments.</jats:p>},

abstract = {<jats:p>Platinum(II) and palladium(II) complexes have been investigated as potential anticancer drugs since the serendipitous discovery of the antineoplastic activities of cisplatin in the 1960s. Skin cancer is considered the most common malignant neoplasm that affects humans, and melanoma is the most lethal type of skin cancer. Surgical excision is the main form of treatment, which also may include radiotherapy, systemic chemotherapy, and immunotherapy. In this work, new insights concerning the structural characterization and in vitro anti-proliferative activity of the palladium(II) complex with the amino acid deoxyalliin (Pd-sac) against a panel of thirteen human tumor cells, with emphasis on skin cancer cell lines, are presented. The composition of the complex was confirmed by elemental analysis as [Pd(C6H10NO2S)2]. The structure of the complex was elucidated for the first time by a single-crystal X-ray diffraction technique. Each deoxyalliin molecule coordinates in a bidentate N,S-mode to palladium(II) in a trans-configuration analogous to the platinum(II) deoxyalliin complex early reported. As the main result, the Pd-sac complex showed a selective anti-proliferative activity against melanoma (UACC-62, TGI = 63.5 µM), while both deoxyalliin and K2PdCl4 were inactive against all cell lines. Moreover, Pd-sac did not affect the proliferation of non-tumorigenic keratinocytes (HaCaT, TGI > 586 µM) and was non-mutagenic in the Ames assay. The results open new perspectives for in vivo studies concerning the application of the Pd-sac complex in the treatment of melanoma.</jats:p>},

abstract = {<jats:p>Leishmaniasis is a group of parasitic diseases with the potential to infect more than 1 billion people; however, its treatment is still old and inadequate. In order to contribute to changing this view, this work consisted of the development of complexes derived from MI metal ions with thioureas, aiming to obtain potential leishmanicidal agents. The thiourea ligands (HLR) were obtained by reactions of p-toluenesulfohydrazide with R-isothiocyanates and were used in complexation reactions with AgI and AuI, leading to the formation of complexes of composition [M(HLR)2]X (M = Ag or Au; X = NO3− or Cl−). All compounds were characterized by FTIR, 1H NMR, UV-vis, emission spectroscopy and elemental analysis. Some representatives were additionally studied by ESI-MS and single-crystal XRD. Their properties were further analyzed by DFT calculations. Their cytotoxicity on Vero cells and the extracellular leishmanicidal activity on Leishmania infantum and Leishmania braziliensis cells were evaluated. Additionally, the interaction of the complexes with the Old Yellow enzyme of the L. braziliensis (LbOYE) was examined. The biological tests showed that some compounds present remarkable leishmanicidal activity, even higher than that of the standard drug Glucantime, with different selectivity for the two species of Leishmania. Finally, the interaction studies with LbOYE revealed that this enzyme could be one of their biological targets.</jats:p>},
