Rimantadine hydrochloride is an RNA synthesis inhibitor that is used as an antiviral agent in the prophylaxis and treatment of influenza.
In a variety of tissue culture systems, rimantadine (25 μg/ml) completely suppressed the growth of dengue virus type 2 in human peripheral blood leukocytes (PBL). Rimantadine significantly inhibited dengue virus replication in cultures of rhesus monkey PBL. In virus-infected LLC-MK2 cell cultures, rimantadine decreased the production of all four types of dengue virus [1]. Rimantadine interfered with the generation of cellular immune responses. Rimantadine hydrochloride inhibited the proliferative response of human peripheral blood lymphocytes to mitogenic and antigenic stimulation. Rimantadine hydrochloride (25 μg/ml) suppressed the responses to phytohemagglutinin, pokeweed mitogen, and concanavalin A by 25, 65, and 90%, respectively. rimantadine (10 μg/ml) significantly inhibited responses to streptokinase-streptodornase, tetanus toxoid, and A2/Aichi influenza vaccine [2]. In a randomized, double-blind trial involving patients with uncomplicated influenza A H3N2 subtype virus infection, rimantadine (200 mg/day for 5 days) significantly reduced nasal secretion viral titers (days 2 through 4), maximal temperature (days 2 and 3), time until defervescence (mean, 37 h shorter), and systemic symptoms [3].

硝酸根从根向地上部茎的长距离运输过程中首先要进行木质部的装载。台湾科学家发现NRT1.5是一个低亲和且依赖于pH的双向转运蛋白,位于质膜并在靠近木质部的中柱鞘细胞中表达,对于硝酸根在木质部的装载具有重要作用。
所以NRT1.5是双向性的转运蛋白
代谢通路:目前在通路数据库(PATHWAY database) 中代谢通路是建立得最好的,有大约90个参考代谢途径的图形。每个参考代谢途径是一个由酶或EC号组成的网络。
