The role of cyclic nucleotide on fetal and neonantal erythropoiesis [PDF]
, 1974 For the purpose to reveal the changes in stimulatory effect of dibutyryl-cyclic- AMP on erythropoiesis during ontogenetic development, the author studied syntheses of DNA, RNA and protein of erythroid cells in fetal liver, neonatal and adult bone marrows

Cyclic AMP Receptor Protein from Yeast Mitochondria [PDF]
, 1985 We have identified and characterized a cyclic AMP receptor protein in mitochondria of the yeast Saccharomyces cerevisiae. The binding is specific for cyclic nucleotides, particularly for cyclic AMP which is bound with high affinity (Kd of 10(-9) M) at 1 ...

Marine Tunicate, the Electuary of Mithridates
Iranian South Medical Journal, 2015 Tunicates are a large group of marine animals and have been named “tunicate” because of cellosic outer covering called a tunic. They are divided into four major classes of the ascidians, thaliaceans, appendicularians and Sorberacea. Ascidians

Synthesis of conformationally restricted cyclic hexadepsipeptides via direct amide cyclization
, 2000 Ring closure by direct amide cyclization was used in the synthesis of 19-membered cyclic depsipeptides 27 (Schemes1 and 3). The linear hexapeptide precursors 4, containing the beta-hydroxy acid 3-hydroxy-2-phenylpropanoic acid (Tro), and five alpha-amino

Total Synthesis of the Marine Cyclic Depsipeptide Lagunamide D
Marine DrugsLagunamide D is a structurally distinct 26-membered cytotoxic cyclic depsipeptide, originally isolated from a marine cyanobacterium. It exhibits potent antiproliferative activity in the low nanomolar range against A549 human lung adenocarcinoma cells and HCT116 colon cancer cells.
