The structure analysis indicates that the reverse symmetry ligand H4LB molecules are linked into a 2D supermolecular network by two types of hydrogen bonds. One type occurs between the oxalamide oxygen group and the phenol hydroxyl qroup of the nearest molecule with d=2.906(2) and ∠O-H…O=151.8°. The other type is between the oxalamide nitrogen group and the oxalamide oxygen group of anther molecule with d=2.849(2),∠N-H…O=158.7°.

晶体结构研究表明配体H4L为顺式桥联分子，晶体中存在两种氢键，一种是草酰胺基团的O原子与苯环上的酚羟基形成O-H…O氢键[d=2.906(2)，∠O-H…O=151.8°]；另一种是草酰胺基团的氨基与相邻草酰胺基上的O原子形成N-H…O氢键[d=2.849(2)，∠N-H…O=158.7°]，通过上述两种氢键将化合物H4LB连接成二维网络结构。

In the cardiovascular system, the endogenous NO, CO, and H2S form three specific and relevant pathways with their corresponding enzymes including nitric oxide syntheses, the home oxygenize and cystathionine-r-lyric enzyme, whose affect can relieve the atherosclerosis.

血管系统中内源性气体信号分子NO、CO、H2S作为一种独特的血管活性物质，分别与其相应的合成酶一氧化氮合酶、血红素加氧酶和胱硫醚－r-裂解酶形成独立而又相互关联的体内重要抗氧化系统，可以减少动脉粥样硬化的严重度。

The journey began with Safraleine, a molecular derivation of saffron and then composed a poem around it, bringing together ingredients of the highest quality such as the essence of Pepperwood and curcuma, the finest coriander, the most luxurious geranium.

旅程从Safraleine番红花开始，将一种接近番红花粉的分子和一首诗结合在一起，然后把所有最顶极的成份像是胡椒和姜黄等香料，最细嫩的胡荽和最奢华的天竺葵等萃取混和在一起。
