Fulminant septic shock caused by Capnocytophaga canimorsus in Italy: Case report

Capnocytophaga canimorsus infection was recently recognized as a zoonosis. We report the first case of fulminant septic shock in Italy caused by this pathogen. The patient, with a history of splenectomy, died at the main hospital in Brescia with a presumptive diagnosis of sepsis. PCR and sequencing on post mortem samples confirmed C. canimorsus as a causative organism. Our purpose is to alert medical professionals to the virulence of C. canimorsus in asplenic and immunocompromised patients. Keywords: Capnocytophaga canimorsus, septic shock, PCR, sequencin

Chiral 8-Amino-5,6,7,8-tetrahydroquinoline Derivatives in Metal Catalysts for the Asymmetric Transfer Hydrogenation of 1-Aryl Substituted-3,4-dihydroisoquinolines as Alkaloids Precursors

Chiral diamines based on an 8-amino-5,6,7,8-tetrahydroquinoline backbone, known as CAMPY (L1), or the 2-methyl substituted analogue Me-CAMPY (L2) were employed as novel ligands in Cp* metal complexes for the ATH of a series of substituted dihydroisoquinolines (DHIQs), known for being key intermediates in the synthesis of biologically active alkaloids. Different metal-based complexes were evaluated in this kind of reaction, rhodium catalysts, C3 and C4, proving most effective both in terms of reactivity and enantioselectivity. Although modest enantiomeric excess values were obtained (up to 69% ee in the case of substrate I), a satisfactory quantitative conversion was successfully fulfilled even in the case of the most demanding hindered substrates when La(OTf)3 was used as beneficial additive, opening up the possibility for a rational design of novel chiral catalysts alternatives to the Noyori-Ikariya (arene)Ru(II)/TsDPEN catalyst

The Challenging Treatment of Cisplatin-Resistant Tumors: State of the Art and Future Perspectives

One of the main problems in chemotherapy using platinum drugs as anticancer agents is the resistance phenomenon. Synthesizing and evaluating valid alternative compounds is challenging. This review focuses on the last two years of progress in the studies of platinum (II)- and platinum (IV)-based anticancer complexes. In particular, the research studies reported herein focus on the capability of some platinum-based anticancer agents to bypass resistance to chemotherapy, which is typical of well-known drugs such as cisplatin. Regarding platinum (II) complexes, this review deals with complexes in trans conformation; complexes containing bioactive ligands, as well as those that are differently charged, all experience a different reaction mechanism compared with cisplatin. Regarding platinum (IV) compounds, the focus was on complexes with biologically active ancillary ligands that exert a synergistic effect with platinum (II)-active complexes upon reduction, or those for which controllable activation can be realized thanks to intracellular stimuli

In vitro anticancer activity evaluation of new cationic platinum(II) complexes based on imidazole moiety

The development and the synthesis of cationic platinum(II) complexes were realized and their cytotoxic activity was tested on triple negative breast cancer MDA-MB-231 cell line and in two cell lines poorly responsive to cisplatin (DLD-1 and MCF-7). The complex 2c resulted the most potent cytotoxic agent in MDA-MB-231 (IC50=61.9 \ub5M) and more effective than cisplatin on both DLD-1 (IC50=57.4 \ub5M) and MCF-7 (IC50=79.9 \ub5M) cell lines. 2c showed different cellular uptake and pharmacodynamic properties than cisplatin, interfering with the progression of the M phase of the cell cycle. Thus, 2c represents a lead compound of a new class of cytotoxic agents with promising antitumor activity
