In Vitro and In Vivo Evaluation of a Nano-Tool Appended Oil mix (Clove and Tea Tree Oil) Thermosensitive Gel for Vaginal Candidiasis. J Funct Biomater 2022; 13:jfb13040203. [PMID: 36412844 PMCID: PMC9680270 DOI: 10.3390/jfb13040203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 10/14/2022] [Accepted: 10/22/2022] [Indexed: 12/14/2022] Open
Abstract
The main objective of the proposed work was the development of a thermosensitive gel (containing clove and tea tree oil) for the management of vaginal candidiasis. Both oils have been recommended to be used separately in a topical formulation for vaginal candidiasis. Incorporating two natural ingredients (clove and tea tree oil) into a product give it a broad antimicrobial spectrum and analgesic properties. The two oils were mixed together at a 3:1 ratio and converted into o/w nanoemulsion using the aqueous titration method and plotting pseudo ternary phase diagrams. Further transformations resulted in a gel with thermosensitive properties. To determine the final formulation's potential for further clinical investigation, in vitro analyses (viscosity measurement, MTT assay, mucoadhesion, ex vivo permeation) and in vivo studies (fungal clearance kinetics in an animal model) were conducted. The current effort leveraged the potential of tea tree and clove oils as formulation ingredients and natural therapeutic agents for vaginal infections. Its synergy generated a stable and effective thermosensitive gel that can be utilized for recurrent candidiasis and other infections.

Abstract
Aim: Flutamide is an outstanding anticancer drug with poor oral bioavailability. This is the first work to investigate the potential of polymersomes versus conventional liposomes to improve flutamide bioavailability. Materials & methods: Polymersomes were prepared by solvent-switching technique and successfully optimized with excellent nanometric size (143 nm) and ζ-potential (-33.4 mV). Physicochemical characterization, stability in gastrointestinal tract and in vivo oral pharmacokinetics in male Sprague–Dawely rats were performed. Results: A significantly higher stability in simulated intestinal fluid was demonstrated by polymersomes compared with liposomes. Great improvement in flutamide oral bioavailability in polymersomes compared with both liposomes and drug suspension was obtained. Conclusion: Polymersomes are promising nanoplatforms to overcome stability problems of liposomes and to improve flutamide oral bioavailability.

Abstract
In this paper, a novel approach to determine stable concentration in API-polymer systems is presented. As a model, binary amorphous mixtures flutamide (FL) drug with a copolymer Kollidon VA64 (PVP/VA) have been used. It is worthwhile to note that finding an effective method to achieve this goal is a matter of great importance because physical stability of the amorphous pharmaceuticals is the key issue that is investigated worldwide. Due to the fact that molecular dynamics was found to be the crucial factor affecting physical stability of disordered pharmaceuticals, we examined it for both neat FL and its PVP/VA mixtures by means of broadband dielectric spectroscopy (BDS). Thorough investigation of the impact of polymeric additive on the molecular mobility of disordered FL reveals unusual, previously unreported behavior. Namely, simultaneously with the beginning of the recrystallization process, we observe some transformation from unstable supersaturated concentration of investigated mixture to the different, unknown concentration of FL-PVP/VA. Observed, during BDS experiment, transformation enables us to determine the limiting, highly physically stable concentration of FL in PVP/VA polymer (saturated solution), which is equivalent to FL + 41% wt. of PVP/VA. The described high physical stability of this unveiled system has been confirmed by means of long-term XRD measurements. According to our knowledge, this is the first time when such a behavior has been observed by means of BDS.

Abstract
In this study, casein (CAS) nanoparticles were used to encapsulate the hydrophobic anticancer drug, flutamide (FLT), aiming at controlling its release, enhancing its anti-tumor activity, and reducing its hepatotoxicity. The nanoparticles were prepared by emulsification of CAS, at pH below its isoelectric point, and stabilized via ionic-crosslinking with sodium tripolyphosphate (TPP). The nanoparticles were spherical and positively charged with a size below 100 nm and exhibited a sustained drug release up to 4 days. After intravenous administration into prostate cancer-bearing rats for 28 days, FLT-loaded CAS nanoparticles showed a higher anti-tumor efficacy as revealed by a significantly higher % reduction in PSA serum level (75%) compared to free FLT (55%). Moreover, the nanoparticles demonstrated a marked reduction in the relative weights of both prostate tumor and seminal vesicle (43% and 32%) compared to free FLT (12% and 18%), respectively. A significantly higher anti-proliferative, anti-angiogenic, and apoptotic effects was demonstrated by the nanoparticles compared to drug solution as evidenced by their ability to decrease the expression of the proliferative marker (Ki-67) and reduce the level of tumor angiogenic markers (VEGF and IGF-1) as well as their ability to activate caspase-3 with subsequent induction of apoptosis in prostate cancer cells. Conclusively, these novel ionically-crosslinked milk protein nanovehicles offer a promising carrier to allow controlled intravenous delivery of hydrophobic anticancer drugs.
