ACS OMEGA 2024; 9:33735-33742. [PMID: 39130588 PMCID: PMC11307275 DOI: 10.1021/acsomega.4c02845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 05/24/2024] [Accepted: 05/27/2024] [Indexed: 08/13/2024]
Abstract
Although metal-organic thin films are required for many biorelated applications, traditional deposition methods have proven challenging in preparing these composite materials. Here, a Co-organic composite thin film was prepared by plasma-enhanced atomic layer deposition (PEALD) with cobaltocene (Co(Cp)2) on polydimethylsiloxane (PDMS), using two very high frequency (VHF) NH3 plasmas (60 and 100 MHz), for use as a tissue culture scaffold. VHF PEALD was employed to reduce the temperature and control the thickness and composition. In the result of the VHF PEALD process, the Young's modulus of the Co-organic composite thin film ranged from 82.0 ± 28.6 to 166.0 ± 15.2 MPa, which is similar to the Young's modulus of soft tissues. In addition, the deposited Co ion on the Co-organic composite thin film was released into the cell culture media under a nontoxic level for the biological environment. The proliferation of both L929, the mouse fibroblast cell line, and C2C12, the mouse myoblast cell line, increased to 164.9 ± 23.4% during 7 days of incubation. Here, this novel bioactive Co-organic composite thin film on an elastic PDMS substrate enhanced the proliferation of L929 and C2C12 cell lines, thereby expanding the application range of VHF PEALD in biological fields.

Preparation of Cu(II), Ni(II), Ti(IV), VO(IV), and Zn(II) Metal Complexes Derived from Novel vic-Dioxime and Investigation of Their Antioxidant and Antibacterial Activities. Chem Biodivers 2022; 19:e202100768.

Abstract
In this work, novel vic-dioxime ligand (LH2 ) containing bound to the N4 -oxime core moiety and its complexes with Cu(II), Ni(II), Ti(IV), VO(IV), and Zn(II) salts have been studied. The structure of the ligand and its complexes were successfully synthesized and characterized using NMR (1 H and 13 C), LC/MS/MS spectrometer, FT-IR and UV/VIS spectroscopy, melting point, and magnetic susceptibility measurements. Vic-dioxime ligand (LH2 ) (1) and its metal complexes ([Cu(LH)2 ] (2), [Ni(LH)2 ] (3), [Ti(LH)2 ]Cl2 (4), [VO(LH)2 ] (5), and [Zn(LH)2 ] (6), respectively) were tested for them in-vitro antibacterial and antioxidant activities. According to the metal chelating results of the study, it was determined that compounds (1), (2), (3), and (6) showed very good activity, and especially compound (2), had a stronger metal chelating capacity due to ligand dissociation from the synthesized metal complexes, which then would chelate Fe(II) in the experimental setting. When microorganisms were evaluated in terms of the % viability effect, it was observed that all compounds had activity against C. Albicans and S. Cerevisiae at rates similar to antibiotics.

J Trace Elem Med Biol 2021; 65:126714.

Abstract
BACKGROUND The number of known boron-containing compounds (BCCs) is increasing due to their identification in nature and innovative synthesis procedures. Their effects on the fungal kingdom are interesting, and some of their mechanisms of action have recently been elucidated. METHODS In this review, scientific reports from relevant chemistry and biomedical databases were collected and analyzed. RESULTS It is notable that several BCC actions in fungi induce social and economic benefits for humans. In fact, boric acid was traditionally used for multiple purposes, but some novel synthetic BCCs are effective antifungal agents, particularly in their action against pathogen species, and some were recently approved for use in humans. Moreover, most reports testing BCCs in fungal species suggest a limiting effect of these compounds on some vital reactions. CONCLUSIONS New BCCs have been synthesized and tested for innovative technological and biomedical emerging applications, and new interest is developing for discovering new strategic compounds that can act as environmental or wood protectors, as well as antimycotic agents that let us improve food acquisition and control some human infections.
