ellipticine/sarcoma

The uptake, cytofluorescence, and cytotoxicity of elliptinium (NMHE) and a series of fluorescent oxazolopyridocarbazoles [amino acid-ellipticine conjugates (AA-NMHE)] were studied in murine sarcoma cells. For all these drugs, the uptake was rapid, directly proportional to the drug concentration, and

The latency-associated nuclear antigen (LANA) encoded by Kaposi's sarcoma-associated herpesvirus (KSHV) plays a major role in maintaining latency and is critical for the perpetual segregation of viral episomes to the progeny nuclei of newly divided cells. LANA binds to KSHV terminal repeat (TR) DNA

In a phase II trial 2 N-Methyl-9-Hydroxy-Ellipticine (NMHE) was administered in weekly infusions of 100mg/m2 over 1 hour to patients with malignant metastases. Prior to injection, the drug was dissolved in 250 ml isotonic glucose. The results were evaluated in 67 patients. Objective regression was

Herpesvirus lytic DNA replication requires both the cis-acting element, the origin, and trans-acting factors, including virally encoded origin-binding protein, DNA replication enzymes, and auxiliary factors. Two lytic DNA replication origins (ori-Lyt) of Kaposi's sarcoma-associated herpesvirus

Thirteen 5,11-dimethyl-6H-pyrido[3,2-b]carbazoles, structurally related to the antitumour drug ellipticine, were tested for their cytotoxicity against the L1210 murine leukaemia cell line and their antitumour activity against both leukaemias and solid tumours. Most of them showed an interesting

The antitrypanosomal and antifiliarial drug suramin is currently under investigation for treatment of advanced malignancies including prostatic cancer, adrenocortical cancer, and some lymphomas and sarcomas. Here we show that suramin is a potent inhibitor of the nuclear enzyme DNA topoisomerase II.
