Comparative studies on the modes of action of the antirhinovirus agents Ro 09-0410, Ro 09-0179, RMI-15,731, 4',6-dichloroflavan, and enviroxime.
Modes of action of five antirhinovirus agents were compared. Ro 09-0410, 4',6-dichloroflavan, and RMI-15,731 were active preferentially against human rhinovirus. Serotypes of the virus varied in their susceptibility to these three agents, whereas Ro 09-0179 and enviroxime showed activity against all the serotypes of the virus tested to date. Ro 09-0410, RMI-15,731, and 4',6-dichloroflavan inact...
متن کاملRo 09-1470 is a selective inhibitor of P-450 lanosterol C-14 demethylase of fungi.
Ro 09-1470 is a new antifungal agent that belongs to a series of compounds characterized by a tetrahydropyran skeleton with glycine and alkenyl side chains and that inhibits P-450 lanosterol C-14 demethylase (P-450(14DM)) of fungi (Y. Aoki, T. Yamazaki, M. Kondoh, Y. Sudoh, N. Nakayama, Y. Sekine, H. Shimada, and M. Arisawa, J. Antibiot. 45:160-170, 1992; S. Matsukuma, T. Ohtsuka, H. Kotaki, H....
متن کاملSingle ascending dose tolerability, pharmacokinetic-pharmacodynamic study of dihydropyrimidine dehydrogenase inhibitor Ro 09-4889.
PURPOSE Ro 09-4889 was designed to enhance the anticancer efficacy of capecitabine (Xeloda) by generating a dihydropyrimidine dehydrogenase inhibitor (DPDi) 5-vinyluracil (5-VU) preferentially in tumor tissues. This study assessed the tolerance to Ro 09-4889 treatment, and related pharmacokinetic and pharmacodynamic data such as inhibition of DPD activity in peripheral blood mononuclear cells (...
متن کاملDirect and specific inactivation of rhinovirus by chalcone Ro 09-0410.
Studies of various analogs related to the antipicornavirus agent, 4',5-dihydroxy-3,3',7-trimethoxyflavone (Ro 09-0179), led to the identification of 4'-ethoxy-2'-hydroxy-4,6'-dimethoxychalcone (Ro 09-0410), a new and different type of antiviral agent. Ro 09-0410 had a high activity against rhinoviruses but no activity against other picornaviruses. Of 53 rhinovirus serotypes so far tested, 46 we...
متن کاملCinnamycin (Ro 09-0198) promotes cell binding and toxicity by inducing transbilayer lipid movement.
Cinnamycin is a unique toxin in that its receptor, phosphatidylethanolamine (PE), resides in the inner layer of the plasma membrane. Little is known about how the toxin recognizes PE and causes cytotoxicity. We showed that cinnamycin induced transbilayer phospholipid movement in target cells that leads to the exposure of inner leaflet PE to the toxin. Model membrane studies revealed that cinnam...
