  • Obesity is a chronic disorder that is a significant risk factor for diabetes, cardiovascular diseases, malignancy, and other chronic diseases. Lifestyle modifications form the basis of most treatments for obesity, but it has become clear that such modifications alone are not enough for many obese patients. When a behavioral approach is insufficient, pharmacological treatment may be recommended. In recent years, the US Food and Drug Administration (FDA) has withdrawn several therapeutic options for obesity due to their side effects, but has approved four novel anti-obesity agents. Until recently, orlistat was the only drug approved for the management of long-term obesity, but the US FDA approved the novel anti-obesity drugs lorcaserin and phentermine/topiramate in 2012, and naltrexone/bupropion and liraglutide in 2014. The present review discusses the different pharmacotherapeutic options for the treatment of obesity.

  • Obesity is increasing worldwide and has become a major health burden in Western societies affecting every third American and every fifth European. Obesity makes a major contribution to morbidity and mortality, predisposing individuals to cardiovascular disease and diabetes. Many new substances are currently being investigated for their usefulness in the pharmacotherapy of obesity. Most anti-obesity drugs can be divided into four groups: those that reduce food intake; those that alter metabolism; those that increase thermogenesis; and those that regulate hormone involved in feeding behavior. In this article we review these and other agents available in various countries for the treatment of obesity. Perhaps more importantly, we have focussed on areas of potential productivity in the future. Over the last 5 or so years, this impetus in obesity research has provided us with exciting new drugs targets involved in the regulation of feeding behavior and cellular mechanism involved in energy expenditure. Recent development in the quest for control of human obesity include the discovery of hormones, neuropeptides, receptors and transcription factors involved in feeding behavior, metabolic rate and adipocyte development. For developing new, perhaps even more specific pharmacological agents, further research is needed to understand the individual different genetic and physiological basis of obesity. It remains the hope of research scientists that in the not too distant future we shall see a new class of anti-obesity drugs arising logically from the molecular biology revolutions.

  • The purpose of this study is analyzed of exploratory research potential as anti-obesity agents of Euiiin-tang. Four Korean databases and 2 Korean Journals (Riss4U, KISS, OASIS, DBPIA, and Journal of Korean Rehabilitation Medicine, Journal of Korean Medicine of Obesity Research) were searched using search word 'individual herbs' and 'obesity', 'weight loss', 'fat', 'hypertension', 'hyperlipidemia', 'diabetes'. Clinical and Experimental Research published in the journal were analyzed, review research, studies of pharmacopunctures and studies of mixed herbal medicine were excluded. We collected 23 studies. Seven studies of Coicis Semen, 10 stdies of Ephedra Herba, 2 study of Angelica gigas Nakai, 3 studies Atractylodis Rhizoma Alba, 1 studies of Glycyrrhiza inflata Batal. Most studies were experiment researches which were composed of in vivo or in vitro, and clinical trial was 5 studies of Ephedra Herba. Main constituent herb, Coicis Semen, Ephedra Herba were thought to represent an anti-obesity effect. Through the result, we can assume to be likely effect of Euiiin-tang as obesity medicine.

  • Intensive lifestyle modifications and anti-obesity medications are essential for obesity treatment. Antiobesity medications should be selected according to the patient's comorbidities, symptoms, and preferences. This case report describes the treatment of a morbidly obese patient with a history of depression, who complained of tingling and numbness after total thyroidectomy for papillary thyroid cancer. Very low-dose controlled-release phentermine/topiramate was prescribed and intensive lifestyle modifications were encouraged. As a result, the patient effectively lost weight and reached a near-normal weight without adverse drug effects. This implies that even an off-label anti-obesity medication low dose may be better for some patients, and the most important factor in obesity treatment is patient-tailored treatment.

  • The aim of this study was to examine the efficiency of Rhodosporidium toruloides as a new tool to evaluate the triglyceride (TG) reduction effects of anti-obesity candidate materials. Unfermented and fermented persimmon leaf hot water extracts (UFPLE and FPLE) were used as anti-obesity agents. The content of TG in R. toruloides treated with FPLE was less than those with UFPLE by about 11% (p < 0.05) relative to the control (R. toruloides incubated in YPD medium without the agents). Fat reduction in 3T3-L1 cells achieved by FPLE was about 13% higher than that achieved by UFPLE.

  • Obesity increases the risk of developing metabolic diseases such as hypertension, type 2 diabetes, hyperlipidemia, and cardiovascular diseases, as well as some cancers. To prevent the occurrence of these diseases and death, it is essential to manage obesity. Though there are several treatments for obesity, lifestyle interventions, such as diet and exercise, and drug therapy are most widely used in clinical practice. Among the anti-obesity drugs available, the weight loss effect of naltrexone/bupropion has been well-proven. We present a case study in which naltrexone/bupropion, a glucagon-like peptide-1 agonist, and a sodium-glucose transporter 2 inhibitor showed significant weight loss and improved metabolic parameters. Additionally, the management of type 2 diabetes and hypertension, which are common diseases in patients with obesity, was also included.

  • 본 논문은 PDMS을 기반으로 한 미세접촉인쇄법을 사용하여 보다 효율적으로 지방세포를 선택적으로 배양접시에 부착시켰으며 패터닝 된 배양접시에서 지방세포가 빠르게 지방분화를 가능하게 하였다. PDMS을 이용한 선택적 표면 처리 방법은 기존의 세포칩 제작과 달리 소량의 유기용매사용, 저가의 장비 사용, 또한 효율적으로 특정 지역 안에서 지방세포를 고정화하고 성장시킬 수 있으며 이를 통해 지방세포의 생리학적 상태를 손쉽게 관찰할 수 있는 분석 기술로 활용된다. 이렇게 구성된 지방세포칩 위에 대표적인 비만 억제제 약물인 Orlistat을 $0.2{\mu}M{\sim}5.0{\mu}M$ 농도로 처리하였을 때 대조군에 비하여 최대 26.5%의 억제 효과가 나타남을 확인하였다. 따라서, 본 논문에서 제안하는 방법을 통하여 다양한 비만 억제제 약물 탐색을 위한 세포칩으로 활용이 가능할 것으로 기대된다.

  • With the COVID-19 pandemic, there is increasing interest in anti-obesity strategies. According to the National Statistical Office, the obesity rate in Korea was 38.3% in 2020 and 37.1% in 2021. Obesity is a risk factor for several severe diseases, including stroke, heart disease, type 2 diabetes, and certain types of cancer. Pinus rigida × Pinus taeda is a hybrid of Pinus rigida Mill and Pinus taeda Linn, and its cones are considered a by-product. Although previous studies have investigated their pharmacological effects on antioxidant activity and protection against oxidative DNA damage, few researchers have explored their potential as functional natural materials. Therefore, we evaluated the anti-obesity effects of the cone of ethyl acetate fraction of P. rigida × P. taeda (ERT), specifically its ability to inhibit lipid accumulation. Our analysis showed that ERT contains phytochemicals (catechin and caffeic acid) which are known to improve immune function and inhibit cell damage. ERT inhibited lipid droplet accumulation at the cellular levels through Oil Red O staining. Furthermore, ERT suppressed the expression of adipogenic transcription factors (PPARγ and CEBP/α) as well as downstream lipogenic target genes (FAS and SREBP-1) thereby inhibiting adipogenesis. ERT also down-regulated key adipogenic markers, including aP2α, while inducing the phosphorylation of AMPK. It has been reported that PPARγ and CEBP/α are expressed in the early stages of adipose differentiation, while SREBP-1 is expressed in the late stage. Therefore, our findings suggest that ERT activates AMPK signaling pathways, which inhibits adipogenic transcription factors (PPARγ, C/EBPα, and SREBP1) and lipogenic genes (FAS and aP2α), thereby blocking lipid accumulation and preventing obesity and related disorders. ERT showed potential as a new resource for developing a functional material for anti-obesity agents.

  • Rhodosporidium toruloides, an oleaginous yeast, can be used as a fast and reliable evaluation tool to screen new natural lipid-lowering agents. Herein, we showed that triglyceride (TG) accumulation was inhibited by 42.6% in 0.1% red radish coral sprout extract (RRSE)-treated R. toruloides. We also evaluated the anti-obesity effect of the RRSE in a mouse model. The body weight gain of mice fed a high-fat diet (HFD) with 0.1% RRSE (HFD-RRSE) was significantly decreased by 60% compared with that mice fed the HFD alone after the 8-week experimental period. Body fat of the HFD-RRSE-fed group was dramatically reduced by 38.3% compared with that of the HFD-fed group.
