So, the series of R + GA may be GlcA(13)Rha and/or GlcA(12)Rha, as well as the previous was the primary component. The detrimental ion MS2 spectrum of RS + GA/R + GA(S) at 419 was outlined in Number S4B, probably the most abundant ion at 255 arose from glyosidic relationship cleavage of B1, indicating the presence of sulfated glucuronic acid and the sulfate ester could be in the C-2 of the GlcA relating to NMR analysis. The less-intensive ion at 243 arose from glyosidic relationship cleavage of Z1, indicating the 13 linkage between GlcA and Rha. The small ion at 183 arose from cross-ring cleavage 0,2A2, indicating the 12 linkage between GlcA and Rha. So, the sequence of RS + GA/R + GA(S) might be GlcA(2SO4)(13)Rha, GlcA(2SO4)(12)Rha, GlcA(13)Rha(4SO4), GlcA(13)Rha(2SO4), and/or GlcA(12)Rha(4SO4). The bad ion MS2 spectrum of R2S + GA/R2 + GA(S) at 565 was outlined in Number S4C. The ions at 255, 193, 321, and 339 arose from your glyosidic relationship cleavages of B1, B2, C1, and C2, respectively. The ion at 255 indicated the presence of the sulfated glucuronic acid. The ions at 225, 243, and 389 arose from your glyosidic relationship cleavages of Y1, Z1, and Y2, respectively. The ions at 225 and 243 indicated the presence of the sulfate ester in the reducing end Tipifarnib (Zarnestra) of rhamnose. The main constructions of R2S + GA/R2 + GA(S) were GlcA(2SO4)(13)Rha(13)Rha GlcA(2SO4)(13)Rha(12)Rha, GlcA(2SO4)(12)Rha(13)Rha, GlcA(2SO4)(12)Rha(12)Rha, GlcA (13)Rha(13)Rha(2SO4), GlcA (13)Rha(13)Rha(4SO4), GlcA(2SO4)(12)Rha(13)Rha(2SO4) and/or GlcA(2SO4)(12)Rha(13)Rha(2SO4). The above results demonstrated the backbone of MS-1 primarily consisted of 3)–l-Rhaand C-4 of (12)-Rharesidues. The branching was composed of sulfated or unsulfated terminal -d-GlcA 0.05, ** 0.01, versus the control group. Anticoagulant activity of MS-1 in vivo was further evaluated by assays of APTT, PT, and TT. No rats were found moribund and bleeding after intravenous injection of heparin and MS-1. Furthermore, the clotting instances had been long term after injection of MS-1 and heparin, indicating that heparin and MS-1 were absorbed. As demonstrated in Number 3A,B, MS-1 indicated significant prolongation effects within the APTT and TT at 2.5 mg/kg, and no prolongation effect on the PT was found (data not demonstrated). Furthermore, the APTT activity of MS-1 experienced exceeded that of heparin at 5 mg/kg. Therefore, MS-1 exhibited strong anticoagulant activity in vivo. Open in a separate windowpane Number 3 Anticoagulant activity and in vivo and platelet aggregation of MS-1. (A) APTT, (B) TT, and (C) platelet aggregation, clopidogrel. * 0.05, ** 0.01 versus control, # 0.05, ## 0.01 versus the heparin or clopidogrel group. MS-1 had a higher anticoagulant activity in vitro than some sulfated polysaccharides from Monostroma varieties [17,18,25,26,27]. It is interesting to note the APTT activity of MS-1 was weaker than that of the sulfated polysaccharide WF3 from , though both of MS-1 and WF3 primarily consisted of 2)–l-Rha 0.05, ** 0.01 versus the control Tipifarnib (Zarnestra) group; # 0.05, ## 0.01 versus the urokinase group. Further, the effect of MS-1 on carotid artery thrombosis in vivo induced by FeCl3 was investigated by monitoring blood flow using urokinase like a research. As demonstrated in Number 5Da, after 3 min of FeCl3 activation, the blood flow of common carotid artery was rapidly reduced to occlusion in all experimental organizations, and no increase in the control group occurred after saline injection. From Amount FTDCR1B 5DbCe, a reversion was within positive control and MS-1 groupings. Effective recanalization price was within MS-1 groupings, and it had been within a dose-dependent way. Obviously, the blood circulation treated with 25 mg/kg of MS-1 risen to 24.22% from the baseline, the blood circulation treated with 50 and 100 mg/kg of MS-1 groupings risen to 51.33% and 83.89%, respectively, which exceeded that of urokinase group. The full total outcomes indicated which the occluded carotid artery could possibly be recanalized after intravenous shot MS-1, and comprehensive recanalization could possibly be attained at a higher focus of MS-1. Carotid artery thrombus takes place in vessels with serious atherosclerotic disease and could embolize to cause transient ischemic attacks and cerebral infarctions, Tipifarnib (Zarnestra) associating with severe iron deficiency anemia and thrombocytosis .
