The present invention provides an amide compound having antibacterial activity, and a bacterial infection control agent for agricultural and horticultural use that contains the amide compound. The novel amide compound of the present invention is represented by General Formula (1):
wherein R is a -CH(R1)(R2) or a -CO(R2) group, R1 is a hydrogen atom or a hydroxyl group, and R2 is a C1-12 alkyl group.

Panclicins AâE, pancreatic lipase inhibitors from Streptomyces, were synthesised in a modular fashion starting with three alkyl(trimethylsilyl)ketenes, two amino acids and a single aldehyde component, (3R)-3-(tert-butyldimethylsilyloxy)decanal 11. The lone stereocentre in 11 which governs the stereochemistry in subsequent steps was generated by Noyori asymmetric hydrogenation. The key step, a Lewis acid catalysed [2+2] cycloaddition of alkyl(trimethylsilyl)ketenes 13aâc to 11, gave three 3-trimethylsilyloxetan-2-ones with good 1,3-asymmetric induction. After C- and O-desilylation the amino acid side chains were introduced using a Mitsunobu inversion.
Cachexia is a metabolic wasting disorder characterized by progressive weight loss, muscle atrophy, fatigue, weakness, and appetite loss. Cachexia is associated with almost all major chronicillnesses including cancer, heart failure, obstructive pulmonary disease, and kidney disease and significantly impedes treatment outcome and therapy tolerance, reducing physical function and increasing mortality

consequently few inhibitors have been described and no structure–activityrelationship study has been performed. This paper describes the first structure–activityrelationship study, in which a series of 23 known and potential rational AMACR inhibitors were evaluated. AMACR was potently inhibited (IC50 = 400–750 nM) by ibuprofenoyl-CoA and derivatives. Potency was positively correlated with inhibitor lipophilicity
α-甲基酰基辅酶A消旋酶(AMACR;P504S)是一种很有前途的治疗前列腺癌和其他癌症的新型药物靶点。由于“外消旋”反应的可逆性和分离差向异构体产品的困难,酶活性的测定很困难;因此,很少有抑制剂被描述,也没有进行结构-活性关系研究。本文描述了第一个构效关系研究,其中评估了一系列 23 种已知和潜在的合理 AMACR 抑制剂。AMACR 被有效抑制(IC 50 = 400–750 nM) 由布洛芬酰辅酶 A 和衍生物制成。效力与抑制剂的亲脂性呈正相关。AMACR 也受到直链和支链酰基辅酶 A 酯的抑制,其效力与抑制剂的亲脂性呈正相关。2-甲基癸酰基-CoA约为。抑制剂比癸酰辅酶 A 强 3 倍,证明了 2-甲基对有效抑制的重要性。还研究了具有修饰的酰基辅酶A核心的消除底物和化合物,并显示它们是有效的抑制剂。这些结果首次证明了合理的 AMACR 抑制剂的构效关系,并且可以通过酰基辅酶 A 的
