Through the optimization of reaction, phthalimide derivatives were obtained in excellent yields through facile one-pot mild condition reaction of phthalic acid with aryl amines that was catalyzed by L-proline. All the products showed weak-to-moderate antioxidant potential, whereas compounds 1 and 4 showed outstanding and potent antioxidant and lipoxygenase enzyme inhibition potential as compared to the standard drug used.
L-proline is a membrane-permeable nontoxic cryoprotectant, and it may therefore be an alternative CPA instead of DMSO and EG for oocyte vitrification.

With addition of L-proline, fermentation process showed the same profile like in control sample, the same growth and final pH of fermentation medium, yet it had remarkable decrease in Rap titre.
This study showed that L-proline and casein hydrolysate had the same effect on callus proliferation developed from mature and immature embryos.
gardneri did not use D-alanine, L-alanine, and hydroxy L-proline. Seven percent of our strains utilized acetic acid, alaninamide, and L-aspartic acid; 27-33% showed a weak positive reaction to acetic acid, alaninamide, D-alanine, and L-alanine; and 7-13% were weakly positive to L-aspartic acid and hydroxy L-proline.
africana does not produce chlamydospores, does not grow at 42[degrees]C, tests negative for L-proline aminopeptidase activity, and grows in rough colonies on bird seed agar, instead of smooth ones.
Using a new enzyme that positionally and stereoscopically hydroxylates L-proline discovered by Professor Dr.
The transitions monitored for each analyte (precursor ion/ product-fragment ion in m/z) were: L-arginine, 175.1/ 43.0, 175.1/60.0, 175.1/70.0; L-arginine internal standard (U-13C6 L-arginine: HCl), 181.0/44.0, 181.0/ 61.1, 181.0/74.1; L-ornithine, 133.1/116.1, 133.1/70.0; L-citrulline, 176.0/113.0, 176.0/70.1; L-proline, 116.1/ 52.8, 116.1/42.0, 116.1/70.0; ADMA, 203.1/46.0; and SDMA, 203.2/172.1.
The most frequently amino acids used in callus culture are glycine, asparagine, L-glutamine, L-proline and L-tryptophan (Kopertekh and Stribnaya, 2003; Saharan et al., 2004; Zaidi et al., 2006).
This stoichiometric ascorbate consumption was also seen when the rate of the uncoupled prolyl 4-hydroxylase reaction was enhanced by the addition of poly(L-proline).
Growth hormones like indol 3-acetic acid (1.0-4.5 [micro]M) and different amino acids (D-Alanine, DL-valine, DL-methionine, L-proline and L-cysteine) were also checked for their effect on the activity of peroxidases (added at different concentration in the reaction mixture).
