En humanos, el factor XI se encuentra codificado por el gen Exhrinseca Purification and characterization of two fibrinolytic enzymes from the marine green alga, Codium intricatum. It is known that species of Chlorophyta synthesized polydisperse heteropolysaccarides with low sulfate casczda, glucoronoxilorhamans, glucoronoxilorhamagalactans and xyloarabinogalactans, some of them with a potent anticoagulant activity Uehara et al.

Similar results of slightly anticoagulant potency were observed but in thrombin time test for C. Biochemical and Biophysical Research Communications 2: Anadyomene stellataCaulerpa cupressoides ChlorophytaLobophora variegata Phaeophyta y Liagora farinosa Rhodophyta. An anticoagulant proteoglycan from the marine green alga, Codium pugni-formis.

Seligsohn U Jul Cladistics of the Bryopsidales: Antimicrobial and cytotoxic terpenoids from tropical green algae of the family Udoteaceae.

Biological activity of extracts from some Mediterranean macrophytes. The extracts of Anadyomene stellata Wulfen C. Bioscience Biotechnology and Biochemistry Journal of Molecular Biology 2: We can concluded that these species can dxtrinseca considered as potentially alternative source of anticoagulant molecules. These molecules have different degree of sulfate in their structure and therefore are capable of substitute heparin Farias et al.


Journal of Clinical Pathology 6: Rhamnan sulfate from cell walls of Monostroma coavulacion.

Other seven species presented a slightly anticoagulant activity. SPB Academic Publishing bv.

Factor de coagulación XI

The extracts were prepared mixing 10 g fresh weight of algal material and 10 ml of phosphate buffer PB 0. Alternatively is possible that algal substances acted impeding the polymerization of fibrin for clot formation. Halimeda discoidea Chlorophyta con actividad semejante a la heparina. Remaining algal material was rinsed with tap water and distilled water.

Structure and anticoagulant activity of sulfated galactans. Standardized plasma coagulation tests thrombin and prothrombin time were used. Cada cadena posee una masa molecular de aproximadamente 80 These variation has been suggested as been influenced by geographical factors such as climate and locality and has been probed with primary metabolites as lectins by Ingram and Fabregas et al.

Hemagglutinins in red sea-weeds.

coagulación – English Translation – Word Magic Spanish-English Dictionary

As anticoagulant time reference 6. In the central and eastern zones there are patches of sea-grass Halodule wrightiithe western part with algae.

The results showed other algae with slightly inhibition of clot formation activity, it is not common to consider this species for further investigation, nevertheless the retardation of formation of clot by Penicillus capitatusa species evolutionary related to Halimeda genus Vroom et al. This work deals with the detection of intrjnseca activity in macroalgae from several localities along the Mexican Atlantic coast.


It is not common that extracts from algae were active in both tests, in the literature are only cascadq examples as Codium fragile subsp. Similar results were detected in Caulerpa cupressoides extracts collected in three occasions, in this case even the total absence of activity was detected in one sample. This fact makes the discovery of new anticoagulant substances a priority issue in research.

British Phycological Journal Recently, a group of scientists had stand out the potentiality of some proteins and proteoglycans capable of interfere with blood clotting cascade, particularly from Codium Matsubara et al. Cytogenetics and Cell Genetics 52 The research effort has been focused on one genus, forgotten the basic detection of different algae as a potential source of alternative anticoagulant molecules.

A fibrinolytic enzyme from a marine cogaulacion alga, Codium latum.
