Biological Activity

Description	Benznidazole (Radanil) is a nitroimidazole derivative having an antiprotozoal activity by interfering with parasite protein biosynthesis, influencing cytokines production and stimulating host phagocytosis.

In vitro
In vitro	Benznidazole (BZL) inhibits the proliferation of leukemic non-adherent cells by controlling cell cycle at G0/G1 cell phase through up-regulation of p27. Growth inhibition induced by BZL is a reversible process, not accompanied by significant cell death. Besides its trypanocidal activity, BZL also has an immunomodulatory effect on macrophages by blocking the transcription of some pro-inflammatory mediators without altering interleukin 10 expression^[1].
Cell Research	Cell lines	THP-1 cells
	Concentrations	0.1, 0.5 or 1 mM
	Incubation Time	24 or 48 h
	Method	20000 cells in 200 mL of complete medium were incubated in quadruplicate in a 96-well plate in the presence of BZL (0.1, 0.5 and 1 mM) or vehicle (0.1% DMSO) for 24 or 48 h and then 20 mL of MTT solution (5 mg/mL in phosphate-buffered saline [PBS]) was added to each well. After 2 h at 37 ℃, the MTT solution was removed and precipitated formazan was solubilized in 200 mL DMSO. Formazan production was then measured at OD545nm in a micro plate spectrophotometer, with DMSO as blank.

In Vivo
In vivo	In mice, oral administration of Benznidazole (100 mg/kg): the time to reach maximum concentration (Tmax) in plasma was 0.83 h, and the maximum concentration (Cmax) in plasma was 41.61 μg/ml. The elimination half-life (t_1/2b) of Benznidazole was 2.03 h, and mean residence time (MRT) was 3.86 h. The volume of distribution (V) and clearance (CL), both as a function of Benznidazole bioavailability (F), were 38.81 ml and 13.29 ml/h, respectively. In Wistar rats treated orally, T_maxs of Benznidazole are 2.0 and 1.1 h, respectively. Tmaxs of 15, 30, or 60 min, depending on the dose, in BALB/c mice following intraperitoneal treatment and Tmaxs of 1 to 5 h for dogs treated orally. Benznidazole can cross the blood-brain barrier and exert its action in cases of central nervous system parasitism. However, other studies have indicated that BNZ has toxic effects in the central nervous system. Dogs orally treated with BNZ presented encephalopathy with multifocal characteristics and clinical, pathological, and neurological disorders that were dose dependent and time dependent. Benznidazole biodistribution occurs broadly, reaching the heart and colon, which are the most relevant organs for T. cruzi infection, and also the spleen, brain, liver, lungs, and kidneys^[2].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
