Cytochrome P450 enzymes (CYPs) are widely distributed among various plant groups and constitute approximately 1% of the total number of protein-coding genes. Extensive studies suggest that CYPs are involved in nearly all molecular processes that occur in plants. Over the past two decades, the identification of CYP genes has expanded rapidly, with more than 40,000 CYP genes and 819 CYP families being discovered.

Dual-specificity phosphatase 2 (DUSP2), a member of the mitogen-activated protein kinase phosphatase family, regulates pancreatic cancer metastasis. However, its role in the hypoxic TME in PDAC remains unknown.

In the title complex, [Ag(ClO(4))(CH(3)OH)(C(18)H(15)P)(2)], the angles around the central Ag(+) ion indicate that it is in a distorted tetrahedral coordination. The coordination sphere of silver is formed by two P atoms of two triphenyl-phosphine ligands, one O atom of a perchlorate anion and one O atom of a methanol mol-ecule. The crystal structure is stablized by a bifurcated inter-molecular O-H⋯O hydrogen bond, involving the O-H donor from methanol and two acceptor O atoms from the perchlorate anion, so forming a zigzag chain propagating in [010].

The asymmetric unit of the title complex, [Ag(4)W(2)S(8)(C(25)H(22)P(2))(3)]·2C(3)H(7)NO, tris-[μ(2)-bis-(diphenyl-phosphino)meth-ane]-3:6κ(2)P:P';4:5κ(2)P:P';5:6κ(2)P:P'-μ(5)-sulfido-2:3:4:5:6κ(5)S-μ(3)-sulfido-1:3:4κ(3)S-tetra-μ(2)-sulfido-1:3κ(2)S;1:4κ(2)S;2:5κ(2)S;2:6κ(2)S-disulfido-1κS,2κS-tetra-silver(I)ditungsten(VI) N,N-dimethyl-formamide disolvate, contains two [WS(4)](2-) anions, four silver cations, three bidentate-bridging bis-(diphenyl-phosphino)methane (dppm) ligands and two N,N-dimethyl-formamide (DMF) solvent mol-ecules. The coordination geometry of each Ag atom is distorted tetra-hedral. Two Ag ions are coordinated by μ(2)-S and μ(5)-S atoms, and by two P atoms from two dppm ligands, while the other two Ag atoms are coordinated by μ(2)-S, μ(3)-S and μ(5)-S atoms, and by one P atom from a dppm ligand.

The structure of the title complex, [Ag(C(12)H(8)N(2))(C(18)H(15)P)]CF(3)SO(3), is based on a distorted trigonal-planar N(2)P coordination of the Ag(I) ion, provided by two N atoms of the bidentate phenanthroline ligand and one P atom of the triphenyl-phosphine ligand. The phenanthroline ligand and one phenyl ring of the triphenyl-phosphine ligand almost lie in one plane (maximum deviation = 0.014 Å from the best planes).
