Concise total syntheses of (±)-7-hydroxy debromo agelastatin A (AglA), (±)-AglA, and 11-nitro AglA are presented based on an identified pseudo-symmetry element. This synthetic strategy was developed based on a desire to improve solubility of this p

We aim to provide a finite element analysis for the elastoacoustic vibration problem. We use a dual-mixed variational formulation for the elasticity system and combine the lowest order Lagrange finite element in the fluid domain with the reduced symm

The structure of tetraphenylphosphonium tetrakis(trimethylsilanolato)ferrate(III), [(C6H5)4P][Fe(OSi(CH3)3)4], has tetragonal (I-4) symmetry, and was refined as an inversion twin. It is an ionic compound consisting of a tetraphenylphosphonium cation

A series of naphthyridinone HIV-1 integrase strand-transfer inhibitors have been designed based on a psdeudo-C2 symmetry element present in the two-metal chelation pharmacophore. A combination of two distinct inhibitor binding modes resulted in poten

In this paper, it is pointed out that the descriptions of alloy phase structures are dependent on structural unit sequence. In the systematic science of alloys (SSA), the alloy phase structures are described by means of the symmetry element sequence

A symmetry analysis of trigonal, cubic, and tetragonal superstructures of the M2X type that are formed in strongly nonstoichiometric compounds MXy with the B1 structure has been performed. The channels of disorder-order transitions MXy → M2X have b

Symmetrical features were observed in the amino acid sequences of some biologically active peptides. It is suggested that this approximate symmetry is reflected in the conformations of the peptides at their respective biological receptors, and has ar

The formulas for calculation of the number of particles in structures of cubic symmetry O h are reported. The numbers of atoms in the shells of cubic symmetry are determined by four structurally invariant numbers and the “quantum number” of the o

The Miura fold pattern, or the Miura-ori, is a flat-foldable origami tessellation with a wide range of engineering applications. In particular, the Miura-ori has been applied to the folding of deployable structures for various architectural applicati
