  • Glutathione s-transferase in thought to play a key role in initiating the detoxication of potential alkylating agents, including pharmacologically active compounds. It is widely accepted that garlic contained allin which is converted to allicin by allinase. Allicin is easily degraded to diallyl disulfide and other components. This report attempted to observe the effect of diallyl disulfide on some biological activities. It was observed that the activity of serum transaminase was not changed by the treatment of diallyl disulfide. The liver cytosolic glutathione s-transferase was significantly increased. where as the microsomal glutathione s-transferase was not increased.

  • It was attempted to observe the effect of garlic on the hepatic purine metabolizing enzymes in this study. The activities of adenosine deaminase, guanase, and uricase in rats were not changed significantly following the feeding of 5% garlic juice. Whereas, garlic juice inhibited significantly the hepatic xanthine oxidase activity compared to control group with the lapse of treated-period. The orate level of serum in rats was significantly decreased by the treatment of garlic juice. The above inhibitory effect of garlic was greater in boiled garlic juice than fresh garlic juice-treated group. These results indicated that, according to the chemical properties of allicin which is unstable in heat, other components than allicin in garlic may regulate the hepatic purine metabolizing enzymes.

  • The allylthio group of allicin and other organosulfur compounds, isolated from garlic, is considered a pharmacophore, and a key structure component of the molecule, which affords biological activities. In the foregoing studies, various 3-alkoxy-6-allylthiopyridazine derivatives (K­compounds) were synthesized, and their biological activities tested in animals. As expected, the various derivatives showed good hepatoprotective activities on carbon tetrachloride-treated mice and aflatoxin B1-treated rats, and chemopreventive activities on hepatocarcinoma cells in rats. Other new pyridazine derivatives, with the oxygen atom at the 3-position of the 3-alkoxy­6-allylthiopyridazine displaced by sulfur (S), were synthesized, and their activities tested in vitro. Thio-K6, one of the sulfur-substituted compounds, showed better chemopreventive activity toward hepatocarcinoma cells.

  • Inflammation is a frequent radiation-induced following therapeutic irradiation. Since the upregulation of adhesion molecules on endothelial cell surface has been known to be associated with inflammation, interfering with the expression of adhesion molecules is an important therapeutic target. We examined the effect if allicin, a major component of garlic, on the induction of intercellular adhesion molecule-l (ICAM-1) by gamma-irradiation and the mechanisms of its effect in gamma-irradiated human umbilical vein endothelial cells (HUVECs).

  • 마늘과 주목의 추출물로부터 참깨, 고추, 무우, 배추의 종자전염성병에 대하여 항균활성을 보인 활성물질을 분리, 동정하여 항균 범위가 넓고 안정성이 있는 종자소독제를 개발하고자 실험한 결과 마늘에서 항균성물질은 allicin($C_6H_{10}OS_2$)으로 분리 동정되었고 그 함유량은 0.62%로 검출되었고 주목에서 항균성물질은 taxol($C_{47}H_{51}NO_{14}$)로 분리, 동정되었고 그 함유량은 0.29%로 검출되었다. 마늘, 주목 추출액을 주성분으로 제제화한 농약을 공시하여 공시병원균에 대한 방제효과를 검정한 결과 10배 농도에서는 방제효과가 높았고 100배 농도에서는 다소 낮았다. 제제의 약해는 없었다.

  • 작물의 구성성분이나 생리활성은 재배지역의 자연환경에 영향을 많이 받는다. 제주 동부와 서부 마늘 재배지역의 토양분석 및 생산된 마늘의 성분분석을 실시하였다. 토양 및 마늘의 대량원소는 동부지역에서 높게 나타났으며 미량원소는 서부지역에서 높게 나타났다. 또한 알리인과 총 페놀 함량은 서부지역에서 높았으며 알리신, 총 피루베이트산, 총 플라보노이드 함량 및 ${\alpha}$-glucosidase 저해활성은 동부지역에서 높게 나타나 지역간 차이가 나타남을 알 수 있었다. 본 연구는 제주에서 재배지역에 따른 마늘 성분의 차이를 이해하는데 도움을 줄 것으로 사료된다.

  • It is well known that conventional chemotherapy and radiation therapy can result in toxicity to both normal cells and tumor cells, which causes limitations in the application of these therapeutic strategies for cancer control. Novel and effective therapeutic strategies for cancers with no or low toxicity for normal cells are a high priority. Therefore, natural products with anticancer activity have gained more and more attention due to their favorable safety and efficacy profiles. Pre-clinical and clinical studies have demonstrated that several representative natural compounds such as resveratrol, epigallocatechin-3-gallate, curcumin, allicin and ginsenosides have obvious anticancer potential. In this article, we summarize autophagy-associated targeting pathways of such natural products for inducing the death of cancer cells, and discuss the core autophagic pathways involved in cancer treatments. Recent advances in the discovery, evaluation and exploitation of natural compounds as therapeutic agents for cancers will provide references and support in pre-clinical and clinical application of novel natural drugs for the treatment of primary and metastatic tumors in the future.

  • Garlic (Allium sativum L.) contains a specific sulfur compound, the S-allyl derivative of L-cysteine sulfoxide, and has long been known for its antimicrobial activity against various microorganisms, including bacteria, fungi, and protozoa. The principal antimicrobial compound of garlic is S-allyl-L-propenethiosulfinate (allicin) which is generated by an enzyme, alliinase (L-cysteine sulfoxide lyase), from S-allyl-L-cysteine sulfoxide (alliin). This compound exists exclusively in Allium as a major non-protein sulfur-containing amino acid. S-Allyl-L-propenethiosulfinate belongs to the chemical group of thiosulfinates and is a highly potent antimicrobial. The potency of garlic extract is reduced during storage since thiosulfinates are unstable and are degraded to other compounds some of which do not have antimicrobial activity. Diallyl polysulfides and ajoene are sulfur compounds derived from allicin that do possess antimicrobial activity. It was recently found that garlic becomes antimicrobial on heating at cooking temperatures, and that the compound responsible for this is allyl alcohol, which is generated from alliin by thermal degradation.
