Inositol

• CAS: 87-89-8
• Catalog Number: ACM87898-2
• Category: Main Products
• Molecular Weight: 180.16
• Molecular Formula: C6H12O6
• Description: Inositol is a unique new botanical complex which is processed from the fruits of Ceratonia Siliqua (carob tree). It is a multi-action tanning compound, which activates the main melanogenesis pathway thus intensifying and maintaining a suntan longer. Since it stimulates both immediate and delayed tanning, it can be applied to 'before-tanning' formulations such as sunscreens, tan accelerators, day facial creams and 'after-tanning' formulations such as tan-prolonging products, after-sun creams and lotions.

Case Study

Inositol Supplementation for the Prevention and Treatment of Lithium-Induced Cardiac Dysfunction in Mice

L'Abbate S, et al. Biomedicine & Pharmacotherapy, 2024, 178, 117287.

This study explores the cardioprotective role of inositol, administered as an 80:1 mixture of myo-inositol and d-chiro-inositol, against lithium-induced cardiac toxicity in C57BL6 mice. Mice were divided into four groups (n=10 per group): a lithium-only group (Li₂CO₃, 8 weeks), a lithium followed by inositol supplementation group (Li_INOdelayed, 8+4 weeks), a group receiving lithium and inositol concurrently for 12 weeks (Li+INO), and an untreated control group. Inositol was delivered via drinking water. Cardiac structure and function were evaluated using echocardiography, electrocardiography, and histopathological analysis. Ventricular tissue was further analyzed for cardiomyocyte size, ERK1/2 signaling, Kv1.5 potassium channel expression, and BNP transcription levels. Inositol effectively attenuated lithium-induced systolic dysfunction, hypertrophy, and arrhythmogenic susceptibility. Notably, concurrent supplementation prevented cardiac damage, while delayed administration reversed established impairments. Inositol's effects were linked to normalization of hypertrophy markers and suppression of ERK1/2 activation. Additionally, inositol alleviated lithium-related injuries in the liver and kidney.

Inositol Supplementation for Improving Growth Performance and Intestinal Health in Juvenile Hybrid Grouper Fed High-Lipid Diets

Li B, et al. Aquaculture Reports, 2024, 39, 102534.

This study investigated the application of inositol in high-lipid diets (16% crude lipid, 51% crude protein) to improve growth performance and intestinal health in juvenile hybrid grouper (♀Epinephelus fuscoguttatus × ♂Epinephelus lanceolatus). Six isonitrogenous and isolipidic diets were formulated with graded levels of inositol: 0% (control), 0.04%, 0.08%, 0.16%, 0.32%, and 0.64%. Fish with an initial average weight of 6.76 ± 0.34 g were fed these diets for 8 weeks. Specific growth rate significantly improved in the 0.08-0.64% inositol-supplemented groups (P > 0.05). Digestive enzyme activities-particularly amylase, lipase, and trypsin-increased with higher inositol concentrations, with statistically significant enhancements observed in all inositol-treated groups (P < 0.05). Histological analysis revealed that inositol supplementation significantly increased plica width, muscularis thickness, and goblet cell numbers (P < 0.05), despite no changes in plica height. Intestinal microbiota analysis showed a higher OTU count and Simpson diversity index in the 0.08% inositol group. Dominant microbial taxa included Proteobacteria and Vibrionaceae. These findings demonstrate that dietary inositol, particularly at 0.08-0.64%, effectively enhances digestive enzyme activity, intestinal morphology, microbial diversity, and growth in hybrid grouper, making it a valuable additive in high-lipid aquafeeds.
