Acta Crystallographica Section E Structure Reports Online, 2011 THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 2-amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 3-phenyl-prop-2-enoate), C(4)H(8)N(3)O(+)·C(9)H(7)O(2) (-), is stabilized by N-H⋯O hydrogen bonding. Cations are linked to anions to form ion pairs with an R(2) (2)(8) ring motif.

Acta Crystallographica Section E Structure Reports Online, 2007 In the crystal structure of the title compound [4-methylphenyl (E)-3-phenylpropenoate], C16H14O2, the benzene ring of the cinnamoyl group is slightly distorted due to conjugation with the double bond. The mean plane of the cinnamoyl group forms a dihedral angle of 61.1 (1)° with the plane of the cresyl group.

Multifunctional Cinnamic Acid Derivatives [PDF]
Molecules, 2017 Our research to discover potential new multitarget agents led to the synthesis of 10 novel derivatives of cinnamic acids and propranolol, atenolol, 1-adamantanol, naphth-1-ol, and (benzylamino) ethan-1-ol. The synthesized molecules were evaluated as trypsin, lipoxygenase and lipid peroxidation inhibitors and for their cytotoxicity.

Cinnamate-based DNA photolithography [PDF]
Nature Materials, 2013 As demonstrated by means of DNA nanoconstructs, as well as DNA functionalization of nanoparticles and micrometre-scale colloids, complex self-assembly processes require components to associate with particular partners in a programmable fashion. In many cases the reversibility of the interactions between complementary DNA sequences is an advantage ...

Sunscreens - Which and what for? [PDF]
, 2005 It is well established that sun exposure is the main cause for the development of skin cancer. Chronic continuous UV radiation is believed to induce malignant melanoma, whereas intermittent high-dose UV exposure contributes to the occurrence of actinic ...
