Curcumin, a hydrophobic polyphenol isolated from the Curcuma longa L. plant, has many pharmacological properties, including antioxidant, anti-inflammatory, and chemo-preventive activities. Curcumin has been shown to have potential in preventing nonalcoholic fatty liver disease (NAFLD). However, the low bioavailability of curcumin has proven to be a major limiting factor in its clinical adoption. Theracurmin, a highly bioavailable curcumin that utilizes micronized technology showed improved biological absorbability in vivo. The aim of this study was to investigate the role of theracurmin in modulating hepatic lipid metabolism in vivo. A fatty liver mouse model was produced by feeding mice a high fat diet (HFD; 60% fat) for 12 weeks. We found that treatment for 12 weeks with theracurmin significantly lowered plasma triacylglycerol (TG) levels and reduced HFD-induced liver fat accumulation. Theracurmin treatment lowered hepatic TG and total cholesterol (T-CHO) levels in HFD-fed mice compared to controls. In addition, theracurmin administration significantly reduced lipid peroxidation and cellular damage caused by reactive oxygen species in HFD-fed mice. Overall, these results suggest that theracurmin has the ability to control lipid metabolism and can potentially serve as an effective therapeutic remedy for the prevention of fatty liver.

The fruit stalk of Hovenia dulcis (H.dulcis) is traditionally used to relieve hangovers in Korea. Theracurmin is a highly absorbable curcumin preparation which increases the bioavailability of curcumin. Curcumin is known for its antioxidant and anti-inflammatory effects. However, the role of this combination in lowering alcohol levels in the body, thereby alleviating the severity of alcohol-induced hangover has not been investigated. Therefore, we conducted a study to investigate the eliminatory effects of a health drink containing the extract of the H. dulcis fruit stalk and theracurmin (theracurmin drink) on ethanol-induced hangover in rats. The theracurmin drink delivered orally to rats 30 mins before the administration of 40% ethanol (5 g/kg body weight), lowered the concentration of ethanol and acetaldehyde in the blood samples collected 1, 3, and 5 h after ethanol administration. Furthermore, the theracurmin drink increased the activities of alcohol dehydrogenase and aldehyde dehydrogenase enzymes. The effectiveness of the theracurmin drink was thus superior to that of other health drink products, suggesting that its consumption may alleviate or prevent an alcohol-induced hangover.

As the elderly population is increasing, Alzheimer's disease (AD) has become a global issue and many clinical trials have been conducted to evaluate treatments for AD. As these clinical trials have been conducted and have failed, the development of new theraphies for AD with fewer adverse effects remains a challenge. In this study, we examined the effects of Theracurmin on cognitive decline using 5XFAD mice, an AD mouse model. Theracurmin is more bioavailable form of curcumin, generated with submicron colloidal dispersion. Mice were treated with Theracurmin (100, 300 and 1,000 mg/kg) for 12 weeks and were subjected to the novel object recognition test and the Barnes maze test. Theracurmin-treated mice showed significant amelioration in recognition and spatial memories compared those of the vehicle-treated controls. In addition, the antioxidant activities of Theracurmin were investigated by measuring the superoxide dismutase (SOD) activity, malondialdehyde (MDA) and glutathione (GSH) levels. The increased MDA level and decreased SOD and GSH levels in the vehicle-treated 5XFAD mice were significantly reversed by the administration of Theracurmin. Moreover, we observed that Theracurmin administration elevated the expression levels of synaptic components, including synaptophysin and post synaptic density protein 95, and decreased the expression levels of ionized calcium-binding adapter molecule 1 (Iba-1), a marker of activated microglia. These results suggest that Theracurmin ameliorates cognitive function by increasing the expression of synaptic components and by preventing neuronal cell damage from oxidative stress or from the activation of microglia. Thus, Theracurmin would be useful for treating the cognitive dysfunctions observed in AD.

커큐민 분말은 항산화 및 항염증 등의 생리활성을 내세우며, 건강기능식품 및 일반식품의 마케팅 포인트로 광범위하게 사용되고 있다. 커큐민의 낮은 체내 흡수율은 생리적 기능성에도 영향을 미칠것으로 사료되어 리포좀 형태나 인지질 결합 형태로 커큐민의 제형 개발이 활발이 진행되고 있다. 본 연구에서는 커큐민의 체내 흡수율을 높이고, 실제 산업에의 활용도를 높이기 위해 커큐민을 서브마이크론 입자 형태의 제형으로 개발하여, 일반 커큐민 형태와의 흡수율을 비교해보고자 하였다. 본 연구 결과, 일반 커큐민 보다 서브마이크론 입자 형태 커큐민의 체내 흡수율이 남녀 평균 28배 더 높게 나타났다. 서브마이크론 입자 형태 커큐민의 체내 흡수율은 성별에 따라 다르게 나타났으며, 남성의 경우는 22배, 여성의 경우는 35배 흡수율이 높게 나타났다. 편의성을 증진시킨 농축제제와 기존 제제의 흡수율은 $C_{max}$ 값이 각각 166.0과 177.7로 통계적 유의성이 나타나지 않았다. 단회 투여 후 8시간 동안의 AUC 값 역시 약 952와 약 849로 나타나 제제의 동등성에서 유의적인 차이는 없었다. 결론적으로, 본 연구를 통해 일반 커큐민 보다 서브마이크론 입자 형태 커큐민의 체내 흡수율이 남녀 평균 약 28배 증진되는 것으로 확인되었으며, 편의성을 증진시킨 농축제제와 일반 제제의 흡수율이 거의 동일하게 나타났다.

Curcumin is a hydrophobic polyphenol extracted from turmeric that exhibits a variety of biological functions has albeit with limited efficacy as a functional food material owing to its low absorption when administered orally. The newly developed curcumin powder formulation exhibits improved absorption rate in vivo. This study evaluates the anti-oxidant effects of $Theracurmin^{(R)}$ (TC), which is highly bio-available in curcumin powder. The antioxidant activity of TC was investigated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, ferrous reducing antioxidant power (FRAP) assays, NO radical, superoxide radical, $H_2O_2$ scavenging activity, and total antioxidant capacity (TAC). Additionally, we evaluated the antioxidant activity of TC in high-fat diet (HFD)-fed streptozotocin (STZ)-induced Type 2 diabetic rats. As a result of oral administration of TC for 13 weeks in type 2 diabetic rats, the group administration of 2,000 mg/kg significantly increased FRAP, superoxide dismutase (SOD), and reduced the level of glutathione (GSH) in liver tissue 1.9, 1.2, and 1.2-times, respectively. Furthermore, serum TAC levels increased by 1.3-fold after the rats were administered with a dose of 500 mg/kg. These results were consistent with the in vitro assay results. In conclusion, TC exhibited its potential as a functional food material through its antioxidant properties.
