DA-11004 is a synthetic, potent NADP-dependent isocitrate dehydrogenase (IDPc) inhibitor where $IC_{50}$ for IDPc is 1.49 $\mu$M. The purpose of this study was to evaluate the effects of DA-11004 on the high fat high sucrose (HF)-induced obesity in male C57BL/6J mice. After completing a 8-week period of experimentation, the mice were sacrificed 1hr after the last DA-11004 treatment and their blood, liver, and adipose tissues (epididymal and retroperitoneal fat)were collected. There was a significant difference in the pattern of increasing body weight between the HF control and the DA-11004 group. In the DA-11004 (100 mg/kg) treated group the increase in body weight significantly declined and a content of epididymal fat and retroperitoneal fat was also significantly decreased as opposed to the HF control. DA-11004 (100 mg/kg) inhibited the IDPc activity, and thus, NADPH levels in plasma and the levels of free fatty acid (FFA) or glucose in plasma were less than the levels of the HF control group. In conclusion, DA-11004 inhibited the fatty acid synthesis in adipose tissues via IDPc inhibition, and it decreased the plasma glucose levels and FFA in HF diet-induced obesity of C57BL/6J mice.

The biological effects of NADPH-dependent isocitrate dehydrogenase (IDPc) inhibitor. DA-11004, was examined in obese zucker rats or streptozotocin-induced diabetic SD rats. Diabetes was induced by injection of streptozotocin (50mg/kg) dissolved in citrate buffer (pH 4.8) into the tail vein and induction of diabetes was confirmed by the measurement of the tail blood glucose level at 48h. DA-11004 (30mg/kg, po) was injected for successive 7days and significantly reduced the plasma glucose in streptozotocin-induced diabetic rats (P<0.05). (omitted)

The biological effects of NADPH-dependent isocitrate dehydrogenase (IDPc) inhibitor, DA-11004, was investigated in obese diabetic (ob/ ob) mice. DA-11004, metformin, and oxalomalate were daily injected (ip) for 8 weeks and after completing an 8-week period of experiment, mice were sacrificed at 1 hr after the last drugs treatment to collect their blood, liver, and adipose tissues(epididymal and retroperitoneal fat).

Recently. it has been known that NADPH-dependent isocitrate dehydrogenase (IDPc) involves in the obesity through production of NADPH, an important cofactor. DA-11004 is a synthetic potent IDPc inhibitor that $IC_{50}$ for IDPc is 1.49$\mu\textrm{M}$ (0.9$\mu$g/ml). The purpose of this study was to evaluate the effects of DA-11004 on the high fat high sucrose (HF)-induced obesity in C57BL/6 mice. (omitted)

Sepsis is a major health problem worldwide, with an extremely high rate of morbidity and mortality, partly due to delayed diagnosis during early disease. Currently, sepsis diagnosis requires bacterial culturing of blood samples over several days, whereas PCR-based molecular diagnosis methods are faster but lack sensitivity. The use of biosensors containing nucleic acid aptamers that bind targets with high affinity and specificity could accelerate sepsis diagnosis. Previously, we used the systematic evolution of ligands by exponential enrichment technique to develop the aptamers Antibac1 and Antibac2, targeting the ubiquitous bacterial peptidoglycan. Here, we show that these aptamers bind to four gram-positive and seven gram-negative bacterial sepsis agents with high binding efficiency. Thus, these aptamers could be used in combination as biological recognition elements in the development of biosensors that are an alternative to rapid bacteria detection, since they could provide culture and amplification-free tests for rapid clinical sepsis diagnosis.

볏짚으로부터 200 bacilli 균주들이 분리되었고 이중 3 균주는 Bacillus cereus ATCC1457를 강력히 저해하였다. 분자생물학적 방법들을 사용하여 이들을 동정한 결과 RSC15는 B. licheniforms로 RSC26과 RSC42는 B. amyloliquefaciens들로 확인되었다. 항균물질들은 내열성을 지녀서 $100^{\circ}C$ 20분 처리 후에도 활성의 절반이 유지되었다. 배양상등액의 SDS-PAGE 분석결과 2종의 다른 항세균물질들이 확인 되었고 이들은 3.5 kDa 이하였다. 컬럼크로마토그래피 방법들을 사용하여 B. licheniformis RSC15가 만드는 항세균물질들을 부분정제한 결과 비활성은 955.0 AU/mg에서 6,400 AU/mg으로 증가하였다.
