in the course of an evaluation of various schistosomicidal drugs in iran, the effect of an organo-phosphorus compound in the-treatment of 45 mild cases of urinary bilhariziasis was assessed and the drug was given in 3 doses of 10 mg/kg body weight each with 3-week intervals. follow-up examinations undertaken 3 weeks after the 1st, 2nd and 3rd doses as well as 3 months after completion of therap...

BACKGROUND Praziquantel (PZQ) is the drug compound of choice in the control and treatment of schistosomiasis. PZQ is administered as a racemate, i. e. 1ratio1 mixture of enantiomers. The schistosomicidal activity arises from one PZQ-enantiomer, whereas the other enantiomer does not contribute to the activity. The WHO's Special Programme for Research and Training in Tropical Diseases (TDR) has a...

Control of schistosomiasis relies on a single drug, praziquantel (PZQ). Given the rising concerns about the potential emergence of PZQ-resistant strains, it has now become necessary to search for novel therapeutics. Efforts have been made for developing new schistosomicidal drugs, or testing existing drugs originally used for non-related diseases. However, the current pace for antischistosomal ...

Background Schistosomiasis remains a severe problem of public health in developing countries [1]. Several reports show that praziquantel, the drug of choice for treating schistosomiasis, can select Schistosoma mansoni strains resistant to the drug. Thus, developing new drugs against this parasitosis is a highly desirable goal [2]. In this context, enzymes involved in energetic metabolism could ...

A series of benzothiazol-2-yl-dithiocarbamates 3a-d along with their copper complexes 4a-c were synthesized via the reaction of suitable alkyl, aralkyl or heteroaryl halides with the sodium salt of benzothiazol-2-yl-dithiocarbamic acid, followed by complexation with copper sulphate. N-(4-Acetyl-5-aryl-4,5-dihydro-1,3,4-thiadiazol-2-yl)-N-benzothiazol-2-yl-acetamides 7a-c were synthesized by cyc...

The conventional PCR technique was used for studying the schistosomicidal effect of Mirazid® in the murine model. Results of the molecular study were compared with the parasitological results (ova and worm count). The used PCR technique was more sensitive than the Kato-Katz thick smears. Mirazid® showed some schistosomicidal effects against murine Schistosoma mansoni. However, it was not effici...

Morbidity and mortality caused by schistosomiasis are serious public health problems in developing countries. Because praziquantel is the only drug in therapeutic use, the risk of drug resistance is a concern. In the search for new schistosomicidal drugs, we performed a target-based chemogenomics screen of a dataset of 2,114 proteins to identify drugs that are approved for clinical use in human...
