persistent cleavage complexes, and induction of a unique pattern of DNAcleavage sites. Molecular modeling has suggested that substituents on the indenoisoquinoline lactam nitrogen would protrude out of the DNA duplex in the ternary cleavage complex through the major groove. This indicates that relatively large substituents in that location would be tolerated without compromising biological activity. As a

A− is NO3− (I), Cl− (II), PF6− (III)). These systems were studied by superconducting quantum interference device (SQUID) magnetometry and X-band electron paramagnetic resonance (EPR) spectroscopy. Magnetic measurements revealed mixed spin states (high spin [HS], low spin [LS]) of Fe (III) ions at room temperatures. Estimates of the corresponding spin contributions were made. It was found that all
我们研究的主要目的是研究以顺磁性铁(III)离子为核心和咔唑光敏衍生物为外围的各种类型的杂化系统。我们合成了多种双配体配位化合物,其组成为[FeL 2 ]A(其中L为2-[2-[(E)-[4-[4-(3,6-二叔丁基咔唑-9-基)苯甲酰基]氧基-2-苯酚酯]亚甲基氨基]乙基氨基]4-(3,6-二叔丁基咔唑-9-基)苯甲酸乙酯,A -为 NO 3 - ( I ), Cl - ( II ), PF 6 - ( III ))。通过超导量子干涉装置 (SQUID) 磁力测量和 X 波段电子顺磁共振 (EPR) 光谱研究了这些系统。磁性测量揭示了室温下 Fe (III) 离子的混合自旋态(高自旋 [HS]、低自旋 [LS])。对相应的自旋贡献进行了估计。结果发现,所有样品均表现出铁 (III) 离子之间的 AFM 交换相互作用。建立并分析了 2.0 K 时的基态自旋态。 EPR 测量证实了铁 (III)
Photoclickable Dendritic Molecular Glue: Noncovalent-to-Covalent Photochemical Transformation of Protein Hybrids
A water-soluble dendron with a fluorescein isothiocyanate (FITC) fluorescent label and bearing nine pendant guanidinium ion (Gu(+))/benzophenone (BP) pairs at its periphery (Glue(BP)-FITC) serves as a "photo-clickable molecular glue". By multivalent salt-bride formation between Gu(+) ions and oxyanions, Glue(BP)-FITC temporarily adheres to a kinesin/microtubule hybrid. Upon subsequent exposure to UV light, this noncovalent binding is made permanent via a cross-linking reaction mediated by carbon radicals derived from the photoexcited BP units. This temporal-to-permanent transformation by light occurs quickly and efficiently in this preorganized state, allowing the movements of micro-tubules on a kinesin-coated glass plate to be photochemically controlled. A fundamental difference between such temporal and permanent bindings was visualized by the use of "optical tweezers".
