Crystal structure of l-leucyl-l-isoleucine 2,2,2-trifluoroethanol monosolvate
Hydro-phobic dipeptides with either l-Leu or l-Phe constitute a rather heterogeneous group of crystal structures. Some form materials with large water-filled channels, but there is also a pronounced tendency to incorporate organic solvent mol-ecules, which then act as acceptors for one of the three H atoms of the charged N-terminal amino group. l-Leu-l-Ile has uniquely been obtained as two dist...
متن کاملN-Methyl-l-leucyl-l-leucine hydrochloride monohydrate
In the title compound C(13)H(27)N(2)O(3) (+)·Cl(-)·H(2)O, obtained by deprotecting the amino and carboxyl groups of an inter-mediate in the synthesis of the cyclic penta-peptide Galaxamide, a number of hydrogen-bonding inter-actions occur including aminium N-H⋯Cl, amide-carboxyl N-H⋯O, water O-H⋯Cl and carbox-yl-water O-H⋯O associations. The aminium N-H⋯Cl⋯H-N bridging extensions give rise to z...
متن کاملInduction of Apoptosis in Lung Cancer Cells by TRAIL and L-leucyl-L-leucine Methyl Ester
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the tumor necrosis factor superfamily that induces apoptosis in many tumor cells. Previous studies suggested that TRAIL treatment might also cause release of lysosomal cathepsin proteases to the cytosol, thus further promoting apoptosis. L-leucyl-L-leucine methyl ester (LeuLeuOMe) is a lysosome-destabilizing agent th...
متن کاملStandard Thermodynamic Functions of Tripeptides N-Formyl-l-methionyl-l-leucyl-l-phenylalaninol and N-Formyl-l-methionyl-l-leucyl-l-phenylalanine Methyl Ester
The heat capacities of tripeptides N-formyl-l-methionyl-l-leucyl-l-phenylalaninol (N-f-MLF-OH) and N-formyl-l-methionyl-l-leucyl-l-phenylalanine methyl ester (N-f-MLF-OMe) were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 350) K. The tripeptides were stable over this temperature range, and no phase change, transformation, association, or thermal d...
متن کاملPrevention of lethal murine graft versus host disease by treatment of donor cells with L-leucyl-L-leucine methyl ester.
Graft vs. host disease (GVHD) remains one of the main problems associated with bone marrow transplantation. The current studies were undertaken to determine whether treatment of the donor inoculum with the anticytotoxic cell compound L-leucyl-L-leucine methyl ester (Leu-Leu-OMe) would alter the development of GVHD in a murine model. Irradiated recipient mice transplanted with a mixture of contr...
