Currently only docetaxel has been approved to be used in the chemotherapy of prostate cancer and new drugs are urgent need. Salen-Mn is a novel type of synthetic reagent bionic and exerts remarkable anticancer activities. However, the effect of Salen-Mn on human prostate cancer has not been elucidated yet. In this study, we found that treatment of PC-3 and DU145 human prostate cancer cells with...

In the crystal structure of the title compound, [Mn(C(3)H(4)N(2))(6)][Mn(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), there are uncoordinated naphthalene-dicarboxyl-ate dianions and two kinds of Mn(II) complex cations, both assuming a distorted octa-hedral geometry. One Mn(II) cation is located on an inversion center and is coordinated by six imidazole mol-ecules, while the other Mn(II) catio...

the complexes of mn(oac)3 and/or mn(acac)3 with nucleic bases and nucleosides (adenine, guanine, xanthine, adenosine and guanosine) have been synthesized in nonaqueous solution. polarographic and spectroscopic (ir and visible) methods have been used to establish the active site(s) on the imidazole and pyrimidine rings in the nucleic bases and nucleosides for the interaction with the mn(iii) com...

Kagome lattices host strongly correlated electronic phases and topological band structures. In Mn${}_{3}X$ ($X$ = Ge, Sn), anomalous transport behavior is induced by chiral antiferromagnetic ordering of the manganese spins. Here, authors measure elastic tensors Mn${}_{3}$Sn discover some largest magnetoelastic coupling ever reported for itinerant antiferromagnets. This highlights importance str...

A series of new manganese phosphonate clusters with unprecedented topologies, [Mn(20)Na(4)O(12)(t-BuPO(3))(12)(O(2)CMe)(16)(H(2)O)(12)].5H(2)O (), [Mn(15)O(6)(MePO(3))(2)(MeCOO)(18)(H(2)O)(12)][MePO(3)H](2).12H(2)O (), and [Mn(t-BuPO(3)H)(2)(phen)(2)].MeCOOH () have been synthesized and characterized. The core of is composed of two folded "butterfly-like" [Mn(4)(mu(3)-O)(2)] units and two trigo...

In the title compound, [Mn(3)(C(8)H(10)O(4))(3)(C(18)H(10)N(4))(2)], one Mn atom and one cyclohexane-1,4-dicarboxylate (chdc) ligand are located on centres of inversion. One of the two independent Mn atoms is seven-coordinate, binding to five carboxyl-ate O atoms from different chdc ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine (L) ligand, while the second Mn atom...

Superoxide dismutase (SOD, EC 1.15.1.1) plays an important antioxidant defense role in skins exposed to oxygen. We studied the inhibitory effects of Al(3+) on the activity and conformation of manganese-containing SOD (Mn-SOD). Mn-SOD was significantly inactivated by Al(3+) in a dose-dependent manner. The kinetic studies showed that Al(3+) inactivated Mn-SOD follows the first-order reaction. Al(...

I . In two experiments with chicks given diets of different manganese content, the effects of vitamin D on the Mn contents of bone and liver and on the retention of 54Mn in bone, liver and the whole body were determined. 2. Vitamin D slightly increased the Mn content of dry fat-free bone but the proportion of Mn to ash remained unchanged and the Mn content of bone was influenced much more by th...

Submonolayer quantities of Mn are deposited on wurtzite GaN 0001̄ . The surface is monitored using reflection high energy electron diffraction, which shows a pattern consisting of 3 reconstruction along 101̄0 , but only 1 along 112̄0 . Diffraction analysis shows that the 3 streak intensity is maximized at 0.86 monolayer of Mn deposition. The results indicate that Mn forms linear chains along the 1...
