Collagenase Type I 是一种蛋白水解酶,主要靶点是胶原蛋白,能够分解胶原蛋白中的肽键。Collagenase 作为一种潜在的治疗选择来分解突出的椎间盘物质,从而减少对附近神经的压迫。Collagenase 可能有助于过度疤痕组织的分解和重组,潜在地改善组织功能和外观。Collagenase 具有治疗椎间盘突出、瘢痕疙瘩、脂肪团、脂肪瘤以及佩罗尼氏病和手掌纤维瘤病等方面的潜力。
Bisucaberin is a siderophore and bacterial metabolite that has been found inA. haloplanktisand has anticancer activity.1,2It inhibits the growth of L1210 and 1MC carcinoma cells (IC50s = 9.7 and 12.7 μM, respectively) and sensitizes fibrosarcoma 1023 cells to macrophage-mediated cytolysis. 1.Hou, Z., Raymond, K.N., O’Sullivan, B., et al.A preorganized siderophore: Thermodynamic and structural characterization of alcaligin and bisucaberin, microbial macrocyclic dihydroxamate chelating agentsInorg.

Ethionamide HCl is the salt form of Ethionamide, a second-line antitubercular agent that inhibits mycolic acid synthesis. Ethionamide is a nicotinamide derivative, with antibacterial activity, used to treat tuberculosis. Although the exact mechanism of action of ethionamide is unknown, it may inhibit the synthesis of mycolic acid, a saturated fatty acid found in the bacterial cell wall, thereby inhibiting bacterial cell wall synthesis. This eventually leads to bacterial cell wall disruption and cell lysis. Ethionamide may be bacteriostatic or bactericidal in action, depending on the concentration of the drug at the site of infection and the susceptibility of the organism involved. It binds with NAD+ to form an adduct.
PD 0305970 is new bacterial gyrase and topoisomerase inhibitor that possess outstanding in vitro and in vivo activities against a wide spectrum of bacterial species including quinolone- and multidrug-resistant gram-positive and fastidious organism groups.
Dalbergioidin exhibits tyrosinase inhibitory activity with an IC50 of 20 mM. It shows a melanin biosynthesis inhibition zone in the culture plate of Streptomyces bikiniensis that has commonly been used as an indicator organism. Dalbergioidin protects MC3T3-E1 osteoblastic cells against H2O2-induced cell damage through activation of the PI3K AKT SMAD1 pathway, suggests that it may be useful in bone metabolism diseases, particularly osteoporosis. Dalbergioidin also ameliorates doxorubicin-induced renal fibrosis by suppressing the TGF-β signal pathway.
Vomifoliol is most likely the immediate precursor of dehydrovomifoliol, because of the organism converted abscisic acid (ABA), to dehydrovomifoliol as the major metabolise, and a cell-free extract exhibits vomifoliol dehydrogenase activity. Vomifoliol and
