Abstract:
The enzyme trypanothione reductase (TR), together with its substrate, the glutathione-spermidine conjugate trypanothione, plays an essential role in protecting parasitic trypanosomatids against oxidative stress and is a target for drug design. Here we show that a naturally occurring spermine derivative, the antihypertensive agent kukoamine A [N1N12-bis(dihydrocaffeoyl)-spermine] inhibits TR as a mixed inhibitor (Ki = 1.8 microM, Kii = 13 microM). Kukoamine shows no significant inhibition of human glutathione reductase (Ki > 10 mM) and thus provides a novel selective drug lead. The correspon

Abstract:
The first total synthesis of kukoamine B bimesylate was completed from 1,4-diaminobutane dihydrochloride in 12 steps with a 11.4% overall yield, and all the steps could be carried out at a kilogram scale. The cyano groups were used as the precursor of amino groups to avoid the competitive reaction delicately. The aza-Michael addition reaction, amidation and hydrogenation of the cyano group sequence was streamlined as a general approach towards the synthesis of polyamine structures.

Abstract:
Kukoamine A (Kuk A) is a naturally occurring bioactive spermine alkaloid found in the root bark of Lycium chinense, and it exerts various therapeutic effects including antioxidant, neuroprotective, anti-inflammatory, and antidiabetic effects. This study evaluated the anti-inflammatory properties of Kuk A against lipopolysaccharide (LPS)-induced inflammation in RAW 264.7 macrophage cells and carrageenan-induced paw edema in rats. Pretreatment of cells with Kuk A significantly inhibited the production of reactive oxygen species, nitric oxide, prostaglandin E2, cyclooxygenase-2 activity, tumor ne

Abstract:
Osteoporosis is an abnormal bone remodeling condition characterized by decreased bone density, which leads to high risks of fracture. Previous study has demonstrated that Lycii Radicis Cortex (LRC) extract inhibits bone loss in ovariectomized (OVX) mice by enhancing osteoblast differentiation. A bioactive compound, kukoamine B (KB), was identified from fractionation of an LRC extract as a candidate component responsible for an anti-osteoporotic effect. This study investigated the anti-osteoporotic effects of KB using in vitro and in vivo osteoporosis models. KB treatment significantly increase
