Protein interaction screening identifies SH3RF1 as a new regulator of FAT1 protein levels.

Mutations and ectopic FAT1 cadherin expression are implicated in a broad spectrum of diseases ranging from developmental disorders to cancer. The regulation of FAT1 and its downstream signalling pathways remain incompletely understood. We hypothesized that identification of additional proteins interacting with the FAT1 cytoplasmic tail would further delineate its regulation and function.

Endogenous thrombin potential as a novel method for the characterization of procoagulant snake venoms and the efficacy of antivenom.

Venom-induced consumption coagulopathy occurs in snake envenoming worldwide but the interaction between procoagulant snake venoms and human coagulation remains poorly understood. We aimed to evaluate an assay using endogenous thrombin potential (ETP) to investigate the procoagulant properties of a range of Australian whole venoms in human plasma and compared this to traditional clotting and prothrombinase activity studies. We developed a novel modification of ETP using procoagulant snake venoms to trigger thrombin production.

1,1'-Fc(4-C6H4CO2Et)2 and its unusual salt derivative with Z' = 5, catena-[Na+]2[1,1'-Fc(4-C6H4CO2-)2].0.6H2O [1,1'-Fc = (eta5-(C5H4)2Fe].

The neutral diethyl 4,4'-(ferrocene-1,1'-diyl)dibenzoate, Fe[eta(5)-(C(5)H(4))(4-C(6)H(4)CO(2)Et)](2) (I), yields (II) (following base hydrolysis) as the unusual complex salt poly[disodium bis[diethyl 4,4'-(ferrocene-1,1'-diyl)dibenzoate] 0.6-hydrate] or [Na(+)](2)[Fe{eta(5)-(C(5)H(4))-4-C(6)H(4)CO(2)(-)}(2)].0.

2-Ferrocenyl-N-(6-methyl-2-pyrid-yl)benzamide.

The title compound, [Fe(C(5)H(5))(C(18)H(15)N(2)O)], a product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-6-methyl-pyridine, crystallizes with two dissimilar mol-ecules in the asymmetric unit. In one mol-ecule, the picoline amide group is directed away from the 2-ferrocenylbenzene moiety (anti) whereas in the other, these are proximate (syn). In the crystal structure, mol-ecules aggregate into dimers via cyclic, asymmetric N-H⋯N inter-actions with graph set R(2) (2)(8), and are further augmented via intra-molecular C-H⋯O=C and inter-dimer C-H⋯π(arene) inter-actions.

2-Ferrocenyl-N-(2-ferrocenylbenzo-yl)-N-(4-methyl-2-pyrid-yl)benzamide.

The title compound, [Fe(2)(C(5)H(5))(2)(C(30)H(22)N(2)O(2))], a 2:1 product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-4-methyl-pyridine, forms a twisted mol-ecular structure in the solid state due to steric effects from the two benzene rings ortho-substituted with ferrocenyl and carbonyl-derived groups. A short intra-molecular C-H⋯π interaction is observed involving a substituted η(5)-C(5)H(4) ring and an ortho H atom of the benzene ring on the opposite side of the mol-ecule. In the crystal structure, there are no classical hydrogen bonds: inter-actions comprise a short C(6)-H⋯π(C(6)) inter-action involving substituted benzene rings and two C-H⋯O=C inter-actions per mol-ecule.

Methyl 2-(4-ferrocenylbenzamido)thiophene-3-carboxylate and ethyl 2-(4-ferrocenylbenzamido)-1,3-thiazole-4-acetate, a unique ferrocene derivative containing a thiazole moiety.

The conformations and hydrogen bonding in the thiophene and thiazole title compounds, [Fe(C5H5)(C20H14NO3S)], (I), and [Fe(C5H5)(C19H17N2O3S)], (II), are discussed. The sequence (C5H4)-(C6H4)-(CONH)-(C4H2S)-(CO2Me) of rings and moieties in (I) is close to being planar; all consecutive interplanar angles are less than 10 degrees . An intramolecular N-H.
