Abstract
In recent years, the application of phytochemicals to prevent or treat diseases has received greater attention. These phytochemicals have little or no toxicity against healthy tissues and are thus considered as ideal compounds. An impressive number of modern drugs are obtained from natural sources based on their traditional value. D-Pinitol is a natural compound that is derived from soy and soy products. It is a potentially active molecule that belongs to the class of inositols. D-pinitol has been pharmacologically evaluated for its potent antioxidant, anti-diabetic, anti-inflammatory, anti-cancer, hepatoprotective, cardioprotective, renoprotective, neuroprotective, immunosuppressive, and anti-osteoporotic efficacies. This review is an attempt to validate the plausible pharmacological effects of D-pinitol using various in vivo and in vitro studies. PRACTICAL IMPLICATIONS: The consumption of plant-based products has been significantly increased all over the world. The active phytochemicals that are found in plants are stated to have numerous health promoting functions for the treatment of diabetes, cancer, inflammation, cardiac diseases, liver dysfunction, and many other. D-Pinitol is abundantly present in soybeans that possess notable therapeutic activities. Understanding the effects of D-Pinitol would potentially help in applying this compound in clinical research for the treatment of different disorders.

Br J Pharmacol 2022; 179:4655-4672. [PMID: 35760415 PMCID: PMC9544772 DOI: 10.1111/bph.15907] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 03/28/2022] [Accepted: 04/21/2022] [Indexed: 12/30/2022] Open
Abstract
Background and Purpose Recent evidence links brain insulin resistance with neurodegenerative diseases, where hyperphosphorylated tau protein contributes to neuronal cell death. In the present study, we aimed to evaluate if d‐pinitol inositol, which acts as an insulin sensitizer, affects the phosphorylation status of tau protein. Experimental Approach We studied the pharmacological effect of d‐pinitol on insulin signalling and tau phosphorylation in the hippocampus of Wistar and Zucker rats. To this end, we evaluated by western blotting the Akt pathway and its downstream proteins as being one of the main insulin‐mediator pathways. Also, we explored the functional status of additional kinases phosphorylating tau, including PKA, ERK1/2, AMPK and CDK5. We utilized the 3xTg mouse model as a control for tauopathy, since it carries tau mutations that promote phosphorylation and aggregation. Key Results Surprisingly, we discovered that oral d‐pinitol treatment lowered tau phosphorylation significantly, but not through the expected kinase GSK‐3 regulation. An extensive search for additional kinases phosphorylating tau revealed that this effect was mediated through a mechanism dependent on the reduction of the activity of the CDK5, affecting both its p35 and p25 subunits. This effect disappeared in leptin‐deficient Zucker rats, uncovering that the association of leptin deficiency, obesity, dyslipidaemia and hyperinsulinaemia abrogates d‐pinitol actions on tau phosphorylation. The 3xTg mice confirmed d‐pinitol effectiveness in a genetic AD‐tauopathy. Conclusion and Implications The present findings suggest that d‐pinitol, by regulating CDK5 activity through a decrease of CDK5R1, is a potential drug for developing treatments for neurological disorders such as tauopathies.

Abstract
The regio- and stereospecific synthesis of O-methyl-chiro-inositols and O-methyl-scyllo-inositol was achieved, starting from p-benzoquinone. After preparing dimethoxy conduritol-B as a key compound, regiospecific bromination of the alkene moiety of dimethoxy conduritol-B and acid-catalyzed ring opening of dimethoxydiacetate conduritol-B epoxide with Ac2 O afforded the desired new chiro-inositol derivatives and scyllo-inositol derivative, respectively. Spectroscopic methods were employed for the characterization of all synthesized compounds. The novel inositols (11-17) had effective inhibition profiles against human carbonic anhydrase isoenzymes I and II (hCA I and II) and acetylcholinesterase (AChE). The novel inositols 11-17 were found to be effective inhibitors against AChE, hCA I, and hCA II enzymes. Ki values were calculated in the range of 87.59 ± 7.011 to 237.95 ± 17.75 μM for hCA I, 65.08 ± 12.39 to 538.98 ± 61.26 μM for hCA II, and 193.28 ± 43.13 to 765.08 ± 209.77 μM for AChE, respectively. Also, due to the inhibitory effects of the novel inositols 11-17 against the tested enzymes, these novel inositols are potential drug candidates to treat some diseases such as glaucoma, epilepsy, leukemia, and Alzheimer's disease.

Abstract
Carbasugars, the carbocyclic analogues of sugars, constitute an important class of natural products with more than 140 members known and have attracted much attention due to their diverse biological activities like anticancer, antibacterial, herbicidal, and various enzyme inhibitory activities. As many carbohydrates are involved in various cellular signaling pathways, there is great interest in synthesis and biological exploration of carbasugars. Herein, we have developed a methodology to install an α,β-unsaturated aldehyde functionality on different inositols and derivatives by vinylogous elimination of the O-protecting group under mildly acidic condition. We have illustrated the versatility and utility of our methodology by the total syntheses of seven carbasugars viz. (-)-MK7607, (-)-gabosine A, (-)-epoxydine B, (-)-epoxydine C, (+)-MK7607, 1-epi-(+)-MK7607 and 1-epi-(+)-gabosine E.

Abstract
D-chiro-inositol, a member of the inositol family, and pinitol, a 3-methoxy analogue of D-chiro-inositol, have been proposed to have antidiabetic, antiinflammatory, anticancer and stamina enhancing effects. We found that supplementing the diet of Drosophila with D-chiro-inositol and pinitol extended adult longevity in both male and female flies. Life span extension was accompanied by protection against oxidative and starvation stresses, improvement in health span, and no reduction in fecundity. Pinitol increased the fly life span, both in dietary restriction and in ad libitum conditions, suggesting that pinitol increased life span in a manner that was independent of the dietary restriction pathway. Nuclear localization of dFOXO increased in D-chiro-inositol and pinitol-fed flies when compared with controls. Pinitol treatment significantly activated JNK and S6K, but not AKT, indicating that the activation of dFOXO by pinitol is acquired by the activation of S6K and JNK signaling. Hence, our study indicated that D-chiro-inositol and pinitol could be novel food-derived antiaging compounds.

Abstract
PURPOSE Osteoclasts (OCs) are multinucleated giant cells that resorb bone matrix. Accelerated bone destruction by OCs might cause several metabolic bone-related diseases, such as osteoporosis and inflammatory bone loss. D-pinitol (3-O-methyl-D-chiro-inositol) is a prominent component of dietary legumes and is actively converted to D-chiro-inositol, which is a putative insulin-like mediator. In this study, we analyzed the effect of D-chiro-inositol on OC differentiation. METHODS To analyze the role of D-chiro-inositol on OC differentiation, we examined OC differentiation by the three types of osteoclastogenesis cultures with tartrate-resistant acid phosphatase (TRAP) staining and solution assay. Then, we carried out cell fusion assay with purified TRAP(+) mononuclear OC precursors. Finally, we analyzed the effect of D-chiro-inositol on OC maker expression in response to the regulation of nuclear factor of activated T cells c1 (NFATc1). RESULTS We demonstrated that D-chiro-inositol acts as an inhibitor of receptor activator of NF-κB ligand-induced OC differentiation. The formation of multinucleated OCs by cell-cell fusion is reduced by treatment with D-chiro-inositol in a dose-dependent manner. In addition, we demonstrated that D-chiro-inositol inhibits the expression of several osteoclastogenic genes by down-regulating NFATc1. CONCLUSIONS We have shown that D-chiro-inositol is negatively involved in osteoclastogenesis through the inhibition of multinucleated OC formation by cell-cell fusion. The expression of NFATc1 was significantly down-regulated by D-chiro-inositol in OCs and consequently, the expression of OC marker genes was significantly reduced. Hence, these results show that D-chiro-inositol might be a good candidate to treat inflammatory bone-related diseases or secondary osteoporosis in diabetes mellitus.

Abstract
AIM OF THE STUDY Labisia pumila has rejuvenating properties that help women to regain the strength and vigour after giving birth (Burkill, 1935) leading us to speculate that Labisia pumila might also modulate the immune matrix as it is one of the important aspect of healthy state of the living body. MATERIALS AND METHODS Studies were carried out for the evaluation of pro-inflammatory cytokines in murine neutrophils followed by expression of T cell-surface markers and corresponding intracellular expression of cytokines related to T helper1 (Th1) and T helper 2 (Th2) activity. RESULTS The ethyl acetate fraction (A001/3b) obtained from ethanolic extract of leaves of Labisia pumila at graded doses (in vitro) showed increased expression of TNF-α, IL-6 and IL-12. IL-12 is a strong inducer of Th1 response in activated CD4+ T cells and accordingly T cell studies were carried out (in vivo). These specific studies showed A001/3b to cause marked stimulation of CD4+ T helper cells and related cytokine expression like IL-2 and IFN-gamma (a potent Th1 inducer), thereby, having a predominant Th1 upregulation pathway. This was further validated by suppression of IL-4 and IL-10 expression which are the Th2 pathway cytokines. CONCLUSION This study showed ethyl acetate fraction (A001/3b) of Labisia pumila to have Th1 upregulating activity and suggests its possible usefulness as a therapeutic agent in immune compromised patients.
