Cinatrins, a novel family of phospholipase A2 inhibitors. II. Biological activities.

Cinatrins A, B and C3 inhibited phospholipase A2 purified from rat platelets in a dose-dependent manner. Cinatrin C3, the most potent component (IC50 70 microM), was noncompetitive with a Ki value of 36 microM. Cinatrins B and C3 also inhibited both porcine pancreas and Naja naja venom phospholipase A2. Inhibition of rat platelet phospholipase A2 by cinatrin C3 was independent of Ca2+ and subst...

Luminacins: a family of capillary tube formation inhibitors from Streptomyces sp. II. Biological activities.

Twelve of the fourteen isolated components of the luminacin family were assayed for activity to inhibit capillary tube formation in vitro. Seven of them showed potent activity with IC50 values of less than 0.1 microg/ml in a rat aorta matrix culture model. Luminacin D, the strongest inhibitor, inhibited both endothelial cell proliferation and capillary tube formation. Morphological observation ...

Reveromycins, new inhibitors of eukaryotic cell growth. II. Biological activities.

Reveromycins A, B, C and D showed inhibitory activity against EGF-stimulated mitogen response in Balb/MK cells. Furthermore reveromycins A, C and D exhibited morphological reversion of srcts-NRK cells, antiproliferative activity against human tumor cell lines and antifungal activity. The effects of reveromycins A, C and D on eukaryotic cells were closely similar to each other, but those of reve...

Secretory phospholipase A2: a multifaceted family of proatherogenic enzymes.

Secretory phospholipase A(2) (sPLA(2)) represents a class of enzymes that hydrolyze phospholipids from cellular membranes and lipoproteins, resulting in multifarious proatherogenic actions in the vessel wall. Proatherogenic actions of sPLA(2) involve lipoprotein remodeling that facilitates proteoglycan binding and formation of lipid aggregates that are rapidly internalized by tissue macrophages...

Biological activities of novel gyrase inhibitors of the aminocoumarin class.

Thirty-one aminocoumarin antibiotics derived from mutasynthesis experiments were investigated for their biological activities. Their inhibitory activities toward Escherichia coli DNA gyrase were determined in two different in vitro assays: an ATPase assay and a DNA supercoiling assay. The assays gave a similar rank order of the activities of the compounds tested, although the absolute 50% inhib...
