Abstract
Since ancient times the oil from date palm pits (Phoenix dactylifera L.) has been used to heal wounds. In order to prove this traditional usage of the pits, this oil was extracted from the pits of the Tunisian cultivar 'Alig' and its physico-chemical properties and the chemical composition were evaluated. The fatty acid profile, evidenced by GC, allowed to classify this oil as an oleic-myristic acid oil with a clear abundance of oleic acid (53.66 %). 1 H and 13 C-NMR as well as FT-IR analyses confirmed the presence of fatty acids in triglyceride forms. Furthermore, in vivo wound healing activity of a cream formulated from the extracted oil was performed, for the first time, using a rat model and was compared to placebo cream and a commercial formulation, MEBO®. This study showed that the test cream promoted the healing of pressure ulcers better than the placebo cream and the MEBO® ointment. The results showed that this vegetable oil is able to improve the healing of infected wounds in rats, thus supporting its traditional use. The contribution of the main oleic, linoleic and myristic acids that can be derived from enzymatic hydrolysis to the healing activity of the whole pits oil was predicted by in silico study and the calculated pharmacokinetics parameters.

[PMID: 34831477 PMCID: PMC8625526 DOI: 10.3390/cells10113255] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 11/18/2021] [Accepted: 11/19/2021] [Indexed: 12/13/2022] Open
Abstract
Idiopathic or sporadic inclusion body myositis (IBM) is the leading age-related (onset >50 years of age) autoimmune muscular pathology, resulting in significant debilitation in affected individuals. Once viewed as primarily a degenerative disorder, it is now evident that much like several other neuro-muscular degenerative disorders, IBM has a major autoinflammatory component resulting in chronic inflammation-induced muscle destruction. Thus, IBM is now considered primarily an inflammatory pathology. To date, there is no effective treatment for sporadic inclusion body myositis, and little is understood about the pathology at the molecular level, which would offer the best hopes of at least slowing down the degenerative process. Among the previously examined potential molecular players in IBM is glycogen synthase kinase (GSK)-3, whose role in promoting TAU phosphorylation and inclusion bodies in Alzheimer’s disease is well known. This review looks to re-examine the role of GSK3 in IBM, not strictly as a promoter of TAU and Abeta inclusions, but as a novel player in the innate immune system, discussing some of the recent roles discovered for this well-studied kinase in inflammatory-mediated pathology.

Drug Repurposing in Dentistry; towards Application of Small Molecules in Dentin Repair. Int J Mol Sci 2020; 21:ijms21176394.

Abstract
One of the main goals of dentistry is the natural preservation of the tooth structure following damage. This is particularly implicated in deep dental cavities affecting dentin and pulp, where odontoblast survival is jeopardized. This activates pulp stem cells and differentiation of new odontoblast-like cells, accompanied by increased Wnt signaling. Our group has shown that delivery of small molecule inhibitors of GSK3 stimulates Wnt/β-catenin signaling in the tooth cavity with pulp exposure and results in effective promotion of dentin repair. Small molecules are a good therapeutic option due to their ability to pass across cell membranes and reach target. Here, we investigate a range of non-GSK3 target small molecules that are currently used for treatment of various medical conditions based on other kinase inhibitory properties. We analyzed the ability of these drugs to stimulate Wnt signaling activity by off-target inhibition of GSK3. Our results show that a c-Met inhibitor, has the ability to stimulate Wnt/β-catenin pathway in dental pulp cells in vitro at low concentrations. This work is an example of drug repurposing for dentistry and suggests a candidate drug to be tested in vivo for natural dentin repair. This approach bypasses the high level of economical and time investment that are usually required in novel drug discoveries.

Chem Biol Interact 2019; 314:108823. [PMID: 31563592 DOI: 10.1016/j.cbi.2019.108823] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Revised: 07/29/2019] [Accepted: 09/13/2019] [Indexed: 12/16/2022]
Abstract
Schizophrenia cannot be treated sufficiently with existing antipsychotic drugs. Taken into account that increased Glycogen Synthase Kinase 3 Beta (GSK-3β) activity is associated with schizophrenia pathophysiology and certain antipsychotics can be able to decrease GSK3β activity, inhibition of GSK-3β activity could be a novel approach for the treatment of schizophrenia. In the present study MK-801, a widely used chemical for the in vivo/in vitro modeling of schizophrenia was selected to evoke a detrimental effect on cellular survival via GSK3β and related proteins. A limited number of studies have reported the curative effects of famotidine, an antiulcer drug, in schizophrenic patients. To the best of our knowledge, no study investigated the molecular mechanism of the beneficial effect of famotidine in the patients. A recent study based on computerized drug modeling software (docking) indicated that famotidine might inhibit the GSK3β activity due to its chemical structure independent from histaminergic receptors. In this study, we aimed to investigate the effects of famotidine on the Akt/GSK-3β/β-catenin signaling pathway on SH-SY5Y neuroblastoma cells in the presence of MK-801. We investigated the effects of famotidine, olanzapine (an antipsychotic drug), and SB 415286 (specific GSK-3β inhibitor), on the basal cellular survival and MK-801 induced neuronal death beside of Akt/GSK-3β/β-catenin protein and gene expressions in SH-SY5Y cells. Cell viability, protein and gene expressions were determined by the real-time cell analysis (xCELLigence) system, western blotting and real-time polymerase chain reactions (Rt-PCR), respectively. Our findings suggested that MK-801 administration decreased cell survival probably via the increasing GSK-3β gene expression and activity in the SH-SY5Y cells. Pre-treatments with famotidine, olanzapine, and SB 415286 prevented MK-801 induced cell death via inhibitory effects on the MK-801 induced GSK-3β activity. Overall, the present results suggest that famotidine has a neuroprotective effect against MK-801 via modulation of the Akt/GSK-3β/β-catenin signaling pathway, an important mechanism in schizophrenia neurobiology.
