Oregonin reduces lipid accumulation and proinflammatory responses in primary human macrophages

Inflammation in the vascular wall is important for the development of atherosclerosis. We have previously shown that inflammatory macrophages are more abundant in human atherosclerotic lesions than in healthy arteries. Activated macrophages produce reactive oxygen species (ROS) that promote local inflammation in atherosclerotic lesions. Here, we investigated the role of oregonin, a diarylheptanoid, on proinflammatory responses in primary human macrophages and found that oregonin decreased cellular lipid accumulation and proinflammatory cytokine secretion. We also found that oregonin decreased ROS production in macrophages. Additionally, we observed that treatment of lipopolysaccharide-exposed macrophages with oregonin significantly induced the expression of antioxidant-related genes, including Heme oxygenase-1 and NADPH dehydrogenase quinone 1. In summary, we have shown that oregonin reduces lipid accumulation, inflammation and ROS production in primary human macrophages, indicating that oregonin has anti-inflammatory bioactivities.

Current status of the chemistry and synthesis of natural antimalarial compounds and natural substances used to alleviate symptoms of diabetes (aldose reductase and a-glucosidase inhibitors)

Atropine, camptothecin, cocaine, digitoxin, digoxin, morphine, pilocarpine, quinine, taxol, vinblastine and vincristine, among others, are important drugs obtained from higher plants and are used clinically. They have also served as lead compounds for the synthesis and modification of more effective and safer drugs, in many cases. In this chapter, drugs used as antimalarial compounds and for the complications of diabetes (aldose reductase and alpha-glucosidase inhibitors) will be discussed. Natural product chemists have isolated as little as 1.0 mg of pure compounds from natural sources and have been able to determine their structures using high resolution instrumental techniques. Organic chemists have synthesized thousands of compounds to produce one new drug on the basis of natural product leads, and pharmacologists and biochemists have tested their biological activity. Recently chemists and pharmacologists have worked together to develop techniques for studying structure-activity relationships using computer graphics and have designed new drugs. Biochemists, molecular biologists and pharmacologists have identified many receptors on which drugs act. Thus, mechanisms of drug action at the molecular level are being identified. From the accumulation of these results structure-activity relationships will lead to the preparation of thousands of useful compounds. We must produce drugs in these ways, because we cannot rely on solely on the limited amount of active compounds produced naturally in plants, in many cases, for a number of reasons. However we need to employ plant extracts themselves, because there are millions of people who cannot buy expensive synthetic drugs in the world and these extracts are widely used by them.

Penetration and performance testing of the HP? Mole for the InSight Mars mission

During the development and the qualification of the Heat Flow Physical Properties Package (HP?) instrument (developed by the German Aerospace Center), which is part of the NASA Mars mission InSight, its self-propelling subsurface probe, the HP? Mole was used in several penetration tests. Here, the performance of the Mole to reach the target depth, to avoid or overcome obstacles on its path, and its directional stability in the subsurface is elaborated. The different test beds and set ups are described and the results are presented. The deep penetration tests (DPT), with the purpose to reach the target depth, are the most important performance tests and therefore the results are investigated in more detail in section 2. Full functional tests (FFT), which showed the performance and degradation of the mechanism inside the Mole, are presented in section 3. Additional penetration and life cycle tests are described in section 4. The testing has demonstrated that the HP? Mole meets all of its penetration requirements with margin.

Novel, potent aldose reductase inhibitors: 3,4-dihydro-4-oxo-3-[[5-(trifluoromethyl)-2-benzothiazolyl]methyl]-1- phthalazineacetic acid (zopolrestat) and congeners

A new working hypothesis that there is a hitherto unrecognized binding site on the aldose reductase (AR) enzyme with strong affinity for benzothiazoles was pursued for the design of novel, potent aldose reductase inhibitors (ARIs). The first application of this hypothesis led to a novel series of 3,4-dihydro-4-oxo-3-(benzothiazolylmethyl)-1-phthalazineacetic acids. The parent of this series (207) was a potent inhibitor of AR from human placenta (IC50 = 1.9 x 10-8 M) and was orally active in preventing sorbitol accumulation in rat sciatic nerve, in an acute test of diabetic complications (ED50 = 18.5 mg/kg). Optimization of this lead through medicinal chemical rationale, including analogy from other drug series, led to more potent congeners of 207 and culminated in the design of 3,4-dihydro-4-oxo-3-[[5-(trifluoromethyl)-2-benzothiazolyl]methyl]-1- phthalazineacetic acid (216, CP-73,850, zopolrestat). Zopolrestat was found to be more potent than 207, both in vitro and in vivo. Its IC50 against AR and ED50 in the acute test were 3.1 x 10-9 M and 3.6 mg/kg, respectively. Its ED50s in reversing already elevated sorbitol accumulation in rat sciatic nerve, retina, and lens in a chronic test were 1.9, 17.6, and 18.4 mg/kg, respectively. It was well absorbed in diabetic patients, resulting in high blood level, showed a highly favorable plasma half-life (27.5 h), and is undergoing further clinical evaluation. An assortment of synthetic methods used for the construction of benzothiazoles, including an efficient synthesis of zopolrestat, is described. Structure-activity relationships in the new series are discussed.

alpha-Keto Acids: Acylating Agents in Organic Synthesis

A significant number of important acyl-transfer reactions, such as direct acylation, ortho acylation, heteroatom acylation, and a diversity of cyclization reactions using the title compound as a key starting material, have been described in recent years. Just like a sleeping beauty, alpha-oxocarboxylic acids were awakened from a 17-year sleep to become important reagents in classical and new acylation reactions. The greener characteristic of the coproduct formed in reactions using alpha-keto acid (only CO2), together with its versatility as a building block in catalytic organic synthesis, accredit it as a candidate to green acylating agent, an alternative to acyl chloride, and other acyl-transfer reagents. This review presents the impressive breakthroughs achieved mainly in the past decade in the development of new catalytic reactions for the formation of C-C, C-N, and C-S bonds using alpha-keto acids.
