Thrombin is the key serine proteinase of the coagulation cascade and, therefore, a suitable target for inhibition of blood coagulation. An extract of Amanita virosa considerably inhibited thrombin (48%), but showed no inhibitory activity on trypsin. On the basis of inhibition selectivity between thrombin and trypsin and potency of thrombin inhibition, A. virosa constitutes a good starting material for the isolation of further compounds that are active against thrombin. Bioassay oriented fractionation of the extract of A. virosa led to the isolation of a complex mixture of triglycerides (TGs), monoacylglycerols (MAGs), free fatty acids (FAs) and ergosterol. The structures of the isolated lipids metabolites were determined on the basis of chemical and spectroscopic evidences.

This study aimed at evaluating the antibiofilm activity of the Red Sea metabolites from green alga Avrainvillea amadelpha, sea cucumber Holothuria atra and costal plant Sarcocornia fruticosa against three biofilm bacterial strains isolated from Jeddah coast. Free fatty acids (FFAs) and other lipoidal matters were extracted from these organisms and analyzed by GC-MS. The composition of lipoidal fractions showed that A. amadelpha is rich by 74% saturated FAs, while sea cucumber H. atra revealed high content (60%) of unsaturated FAs. Palmitic acid is the major FA component in all species ranging from 14.5 to 26.7%. Phytol, sterols and hydrocarbons (C8-C29) were represented in the alga A. amadelpha as high contents with values 25.8, 21.9 and 18.5%, respectively. The extracts and lipoidal contents showed biofilm inhibitory activity against the isolated bacterial strains, where the unsaponified lipoidal fraction of S. fruticosa exhibited highest inhibitory activity against Planomicrobium sp. at concentration of 200 µg/mL.

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.
