Optimizing the control of apoptosis by amide/triazole isosteric substitution in a constrained peptoid.
Apoptosis is a biological process relevant to several human diseases that is strongly regulated through protein-protein complex formation. We have previously reported a peptidomimetic compound as potent apoptotic modulator. Structural studies of this compound showed the presence of cis/trans isomers of the exocyclic tertiary amide bond in slow exchange. This information encouraged us to perform...
متن کامل3-(4-Nitrophenyl)-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(8)H(6)N(4)O(2)S, the 1,2,4-triazole ring and the nitro group form dihedral angles of 6.26 (13) and 9.5 (3)°, respectively, with the phenyl ring. In the crystal, the mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, generating [010] chains which contain R(2) (2) (8) ring motifs. The crystal structure is further stabilized by π-π stacking [centroid-centroid distanc...
متن کامل3-Benzyl-4-ethyl-1H-1,2,4-triazole-5(4H)-thione
The title compound, C(11)H(13)N(3)S, exists in the 5-thioxo tautomeric form. The benzene ring exhibits disorder with a refined ratio of 0.77 (2):0.23 (2) for components A and B with a common bridgehead C atom. The 1,2,4-triazole ring is essentially planar, with a maximum deviation of 0.002 (3) Å for the benzyl-substituted C atom, and forms dihedral angles of 88.94 (18) and 86.56 (49)° with the ...
متن کامل4-Amino-3-phenyl-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(8)H(8)N(4)S, the planar triazole ring forms a dihedral angle of 13.7 (2)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H⋯S hydrogen-bond inter-actions, linking the mol-ecules into chains along the a axis.
متن کامل3-Ethyl-1H-1,2,4-triazole-5(4H)-thione
The mol-ecule of the title compound, C(4)H(7)N(3)S, exists as the thione tautomer in the solid state. The asymmetric unit consits of one mol-ecule in which all atoms are located on a crystallographic mirror plane. In the crystal, adjacent mol-ecules are linked by N-H⋯N and N-H⋯S hydrogen bonds into chains running along the a axis. π-π stacking inter-actions between the triazole rings [centroid-...
