Heterocyclic compounds of Formula (I) shown herein. Also disclosed is a pharmaceutical composition containing one of the heterocyclic compounds. Further disclosed are methods of using one of the heterocyclic compounds for mobilizing hematopoietic stem cells and endothelial progenitor cells into the peripheral circulation, and for treating tissue injury, cancer, inflammatory disease, and autoimmune disease.

Decorating the Second Coordination Sphere in Pyrazolate‐Based Dinickel(II) Complexes with H‐Bond Donors
bis(2-pyridinylmethyl)aminomethyl or (2-pyridinylmethyl)[2-(1-methylimidazolyl)methyl]aminomethyl chelate arms have been further elaborated by attaching pivaloylamido groups to the outer pyridine rings, giving the new ligands H3L1 and H3L2. The peripheral pivaloylamido groups may serve as potential H-bond donor or acceptor sites towards substrates in the bimetallic cavity. Protonation constants of the new ligand
通过将新戊酰胺基团连接到外吡啶环上,进一步阐述了具有双(2-吡啶基甲基)氨基甲基或(2-吡啶基甲基)[2-(1-甲基咪唑基)甲基]氨基甲基螯合臂的基于吡唑啉的配体,从而得到了新的配体H3L1 和 H3L2。外围的新戊酰氨基可用作双金属腔中朝向基底的潜在 H 键供体或受体位点。新配体 H3L1 的质子化常数及其在溶液中的镍 (II) 形态已通过 pH 电位测定法进行了研究,表明金属结合水的 pKa = 8.9。基于 [Ni2(H2L1)(H3O2)(MeCN)2](ClO4)2 (3) 的 X 射线晶体结构,该 pKa 被合理化为两个平衡效应,即新戊酰氨基 O 原子参与新戊酰氨基 NH 基团和所得镍结合氢氧化物之间的金属配位和 H 键合。配合物3在双金属腔内具有一个吡唑酯桥连的二镍(II)核和一个桥连的HO…H…OH单元,参与多个氢键相互作用。
