Antitumoral uses

The comparison of the two sets of %ILS values allows us to conclude that MYKOMET 63 appears to be actually as active as MYKO 63, but not more active. In other words, the graft of methylated aziridinyl ligands on a six-membered cyclophosphazene ring does not significantly improve the antitumoral activity with respect to the non-methylated isologues. However, because MYKOMET 63 possesses only a slight toxicity compared to MYKO 63, the new drug reported here may be of interest for eventual clinical use, no matter what difficulties are encountered in its synthesis. 

Adalimumab is a recombinant, fully human antitumor necrosis factor monoclonal antibody approved in the US and Europe for the treatment of adult patients with moderate to severe, active rheumatoid arthritis. It has to be injected subcutaneously. The most common side effects of adalimumab are injection site reactions. Adalimumab increases the risk of rare serious infections. Rare side effects include worsening or initiation of congestive heart failure, a lupus-like syndrome, a promotion of lymphoma, medically significant cytopenias, and worsening or initiation of a multiple sclerosis like neurological disease.

While we suspected that there are a total of nine variations in halichondrin A, we have not identified all of them, mostly due to issues regarding limited quantities. The antitumor activities of halichondrin have been clarified by in vivo experiments, and it appears to be a promising compound. However, toxicity has always been an issue. In a joint Japan-US science seminar on cancer research held in Hawaii in 1987,... 

In our continuing search for potential anticancer agents, GL331 (4), which is currently in Phase Ha clinical trials, highlights our current study. However, in all, over the last several years, we have found more than 100 new cytotoxic antitumor compounds and their analogs with confirmed activity in the NCI in vitro human tumor cell lines bioassay. These compounds are of current interest to NCI for further in vivo evaluation and to us for further...

Bryophytes are divided into three classes, Musci, Hepaticae (liverwort) and Anthocerotae, which are known to include 14000,6000 and 300 species, respectively. Various kinds of biologically active compounds have been discovered from bryophytes. For instance there are compounds with hot or bitter taste, ichthyotoxicity, insect antifeedant, antiinflammatory, antimicrobial, antifungus and antitumor activities (1). In liverworts, there exist oil bodies, while in Musci, no oil bodies are present. This can help us to identify the liverworts. 

In the present chapter, we will attempt to give an overview of one very important chemieal genomics tool that we have recently synthesized in our laboratories it is the antitumor alkaloid, (-)-agelastatin A. Its synthesis was undertaken solely for the purpose of helping us answer some important questions we had concerning the workings of the... 

Although not listed in the tables, at least four other natural product drugs have given yeoman service in the antitumor area. The first of these is paclitaxel (Taxol ) which sold US 1.6 billion in 2000 this is followed by the vinca alkaloids vinblastine and vincristine. Completing the quartet are the natural product-derived epi-podophyllotoxin derivatives teniposide and etoposide and the materials derived from camptothecin, topotecan and CPT-11. These will probably not be the only natural product drugs in the antitumor field, as can be seen by inspection of Table 6.3, where Cragg and Newman recently reported on the source...

One of the most successful antitumor compounds is paclitaxel, whose structure is among the most complicated (Fig. 3.10). An anticancer screening study carried out in the US during the 1960s revealed that the extract of the bark of pacific yew (Tams brevifolia) shows very marked antitumor activity. The compound responsible for the effeets, paehtaxel, was duly isolated, but since the quantity in the bark was minisenle, its ehemieal structure was way too complicated for atty financially...
