Anionic polymers with membrane permeation functionalities are highly desirable for secure cytoplasmic drug delivery. We have developed tritryptophan containing copolymer (P/WWW) of polymalic acid (PMLA) that permeates membranes by a mechanism different from previously described PMLA copolymers of
Antipyretic activity of new compounds, 4-(3-oxo-1,2-benzisothiazolin-2-yl)phenylalkanoic acids, their esters, amides and 1,1-dioxide derivatives has been studied. The acid compound of the benzoic series (I:a), tested at graded doses, exerted a noticeable antipyretic action; it had two times the
We have investigated the effect of protease inhibitors on hyperthermic cell killing using cultured mammalian cells (L5178Y) and found that protease inhibitors were potent hyperthermia sensitizers. At 37 degrees C, phenylmethylsulfonyl fluoride (PMSF), a serine protease inhibitor, was not cytotoxic
A phase I study of YM-881 (zinostatin stimalamer), neocarzinostatin combined with butylesterified styrene maleate, suspended in iodized poppy oil ethyl ester, was conducted in patients with hepatocellular carcinoma by giving single intra-arterial infusions via catheters inserted by Seldinger's
Nonsteroidal anti-inflammat ory drugs (NSAIDs) are one of the drug types frequently prescribed for their analgesic, anti-inflammatory, and antithrombotic actions, but carry a risk of major gastroduodenal damage from mild erosive changes to serious ulceration leading to fatal outcomes. From the long
SM-11355 is a platinum complex developed to treat hepatocellular carcinoma (HCC). It is administered via the hepatic artery, using a carrier, lipiodol, that consists of ethyl esters of iodized poppy seed oil. We have performed a phase I clinical trial of an SM-11355-lipiodol formulation in 11 HCC
A method is described for the measurement of soluble thrombin-altered fibrinogen (circulating fibrin) in human plasma. This method is dependent upon the enzymatic incorporation of glycine ethyl ester-(14)C (GEE-(14)C) into circulating fibrin by the action of the fibrin-stabilizing enzyme, factor
We have recently described GS 4071, a carbocyclic transition-state analog inhibitor of the influenza virus neuraminidase, which has potent inhibitory activity comparable to that of 4-guanidino-Neu5Ac2en (GG167; zanamivir) when tested against influenza A virus replication and neuraminidase activity
