The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy-carbazole and 3,3-dimethyl-acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the -CMe(2)- group, the mol-ecule is not quite planar. In the crystal structre, strong N-H⋯O hydrogen bonds and weaker C-H⋯π inter-actions occur, and a slipped π-π stacking inter-action [centroid-cent...
The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-8-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. Due to the -CMe(2)- group, the mol-ecule is not quite planar. The packing is dominated by the strong N-H⋯O hydrogen bonds and some weaker C-H⋯O and C-H⋯π inter-actions. π-π Stacking inter-actions [centroid-centroid separation ...
The mol-ecule of the title compound, C(17)H(13)NO(2), is nearly planar, the r.m.s. deviation for all non-H atoms excluding the two methyl C atoms being 0.089 Å. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds are found in the crystal structure. C-H⋯π inter-actions are also found. The H atoms of the methyl group attached to the benzene ring are disordered equally over two positions.
The title compound, C(21)H(21)NO, consists of a carbazole skeleton with a meth-oxy-benzene ring fused to the carbazole, and a butyl group attached to the carbazole N atom. The carbazole skeleton is nearly planar [maximum deviation = 0.078 (2) Å], and it is oriented at a dihedral angle of 4.22 (4)° with respect to the adjacent meth-oxy-benzene ring.
A computational strategy based on comparative molecular fields analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) was performed on a series of the 11H-dibenz[b,e]azepine and dibenz[b,f][1,4]oxazepine derivatives as potent agonists of the human TRPA1 receptor. The CoMFA and CoMSIA models resulting from a 21 molecule training set gave r²(cv) values of 0.631 and 0.542 ...
The benzo[e]pyrimido-[5,4-b]diazepine-6(11H)-one core was discovered as a novel ERK5 (also known as MAPK7 and BMK1) inhibitor scaffold, previously. Further structure-activity relationship studies of this scaffold led to the discovery of ERK5-IN-1 (26) as the most selective and potent ERK5 inhibitor reported to date. 26 potently inhibits ERK5 biochemically with an IC₅₀ of 0.162 ± 0.006 μM and in...
The title compound, KNa[H(6)PtMo(6)O(24)]·11H(2)O, contains a discrete hexa-molybdoplatinate(IV) [H(6)PtMo(6)O(24)](2-) poly-anion (1 symmetry), which has the highest level of protonation. Five O atoms of the central PtO(6) octa-hedron (μ(3)-atoms, Oc) and one O atom of an outer edge-sharing MoO(6) octa-hedron (O bridging μ(2)-atom, Ob) are protonated. The polyanions are connected by almost lin...
Marine pyridoacridines are a class of aromatic chemicals that share an 11H-pyrido[4,3,2-mn]acridine skeleton. Pyridoacridine alkaloids display diverse biological activities including cytotoxicity, fungicidal and bactericidal properties, production of reactive oxygen species (ROS) and topoisomerase inhibition. These activities are often dependent on slight modifications to the pyridoacridine ske...
