Certain thiazole-containing water-soluble glycosylated polyamides were synthesized and preliminary anticancer evaluation carried out against three types of cancer cells. Glycosyl moieties were introduced onto the polyamide backbone in order to increase the water solubility of the longer polymers <2003EJO4842>.

The antioxidant and anticancer evaluation of Scindapsus officinalis (Roxb.) Schott fruits has been attempted to investigate its antitumor activity [29]. The collection and authentication of the plant material, mainly fruits, and their various extractions were done. Identification of plant s active constituents by preliminary phytochemical screening was carried out. An in vitro cytotoxic assay using the brine shrimp lethality assay with brine shrimp eggs (Artemia salina) at a dose of 1-10 pg/ml with the fmit extract was performed.

Many other bisben2ylisoquinoliae alkaloids, such as tetrandriae (80), from Cjcleapeltata Hook., are also known. Compound (80), for example, although it causes hypotension and hepatotoxicity ia mammals, ia other tests, possessed enough anticancer activity to be considered for preclioical evaluation (55). The arrow poison tubocurare prepared from Chondrendendron spp. also contains the bisben2yhsoquiQoline alkaloid tubocurariae (9). 

Hydrazine sulfate [10034-93-2] N2H4 H2SO4, originally advanced by the Syracuse Cancer Research Institute for treatment of cancerous cachexia and tumor inhibition (221), now has Investigational New Dmg (IND) status in the United States. Clinical evaluations are under way at various institutions such as Harbor-UCLA Medical Center (222) and the Mayo Clinic. After extensive trials, hydrazine sulfate has been approved as an anticancer dmg in Russia (223). Chemical stmctures for estabUshed dmgs in the United States may be found in Reference 224. 

In the veterinary as in the human patient, neoplasms are often metastatic and widely disseminated throughout the body. Surgery and irradiation are limited in use to weU-defined neoplastic areas and, therefore, chemotherapy is becoming more prevalent in the management of the veterinary cancer victim (see Chemotherapeutics, anticancer). Because of the expense and time involved, such management must be restricted to individual animals for which a favorable risk—benefit evaluation can be made and treatment seems appropriate to the practitioner and the owner. In general, treatment must be viewed not as curative, but as palliative. 

We decided to apply the elimination-based dendritic system to the synthesis of an anticancer prodrug and to evaluate it in a tumor cell cytotoxicity assay. Dendritic prodrugs 20 and 21 were synthesized with the chemotherapeutic drug melphalan as a tail unit and a trigger that is activated by PGA (Fig. 5.14). 

Then, we evaluated the enzymatic activation of a second-generation dendritic prodrug with camptothecin (CPT), an anticancer agent, in place of the reporter groups (dendron 38). 

Most of the l,2,4-triazino-l,2,4,5-tetrazine derivatives 4 have been evaluated in vitro for antitumor activity. Results showed that these compounds exhibited a moderate anticancer activity toward leukemia <2003PS2055>. For biological activities of the previous compounds discussed in CHEC-II(1996), please refer to the same <1996CHEC-II(8)743>.

The initial strategy for Phase I is to conduct a single-dose safety study in normal volunteers. The first trial demands close 24-hour supervision in a clinical setting. Ethical considerations may, however, demand that only patients be used, for example, when evaluating an anticancer agent with predictable toxicity. A repeat dose tolerance and pharmacokinetic study in normal or patient volunteers is then conducted for chronically administered drugs. These studies will provide the necessary safety information to support efficacy testing.
