Synthesis of two new water-soluble mixed ligand [Pd(bpy)(dahmp)]Cl and [Ag(bpy)(Hdahmp)]NO(3) complexes (dahmp and Hdahmp are the deprotonated monoanion and the protonated neutral 4,6-diamino-5-hydroxy-2-mercaptopyrimidine, resp.) is reported. The composition of the reported complexes was discussed on the bases of IR, (1)H NMR, and mass spectra, as well as conductivity and thermal measurements....

The effects of a number of alkylating agents on the in vitro incorporation of glycine1-C ~4 into the ethanol/acetone-insoluble fraction of Ehrlich ascites carcinoma cells have been studied. With the exception of 1:6-dimethanesulfonyl-D-mannitol, all inhibit (at the concentrations tested) this incorporation in varying degrees, with little or no effect on the respiration of the cells. The process...

We evaluated the preventive and therapeutic effects of aqueous suspensions of garlic, tomato, and garlic + tomato in the development of experimental Ehrlich tumors in mice. The aqueous suspensions (2%) were administered over a short term for 30 days before tumor inoculation and 12 days afterward, and suspensions at 6% were administered for 180 days before inoculation and for 12 days afterward. ...

Aloe vera (Syn Aloe barbadensis Mill.), a medicinal plant, has a great potential in cosmetic and drug industry due to presence of more than 200 bioactive compounds. Natural propagation of Aloe vera, by means of suckers, is very slow and insufficient to meet the increasing demand of pharmaceutical and cosmetic industries. Shoot tip was used as an explant for in vitro regeneration of Aloe vera. E...

An antibiotic, identical with naphthomycin, was isolated from a soil Streptomyces. The antibiotic displayed significant therapeutic activity by ip administration against murine tumors: Ehrlich carcinoma and IMC carcinoma implanted ip. The maximum increase of life-span was more than 169% in Ehrlich carcinoma, and 128% in IMC carcinoma. The antibiotic exhibited a potent cytotoxicity against murin...

Azaserine has been shown to be a potent in hibitor of de novo purine synthesis in both solid tumors (1, 13) and ascites cells (5, 6, 10). The duration of inhibition has been correlated with increases in the survival time of tumor-bearing hosts (7, 8). During inhibition of de novo purine synthesis by azaserine, the ascites cells maintain the ability to utilize preformed purines and pre sumably s...

The antitumor activity of anti-infective drugs containing iodine complex with bio-organic ligands and potassium and lithium halides (LiCl (I)I2-a-dextrin-peptide) has been experimentally studied. It is shown that the combined action of the drug containing LiCl (I)I2-a-dextrin-peptide complexes and doxorubicin on the growth of Ehrlich ascites carcinoma (EAC) significantly enhanced the antitumor ...

The solvency of solutes of varying molecular size in the intracellular water of freshly-killed Ehrlich carcinoma cells fits the same theoretical curve that describes the solvency of similar solutes in a 36% solution of native bovine hemoglobin--a protein found only in red blood cells and making up 97.3% of the red cell's total intracellular proteins. The merging of the two sets of data confirms...

The creatine/creatine kinase system decreases drastically in sarcoma. In the present study, an investigation of catalytic activities, western blot and mRNA expression unambiguously demonstrates the prominent expression of the creatine-synthesizing enzymes l-arginine:glycine amidinotransferase and N-guanidinoacetate methyltransferase in sarcoma, Ehrlich ascites carcinoma and Sarcoma 180 cells, w...
