| Abstract It is understood that drugs regardless of their order of administration can exhibit drug interactions. Established on the fact that treatment of hypertension may last for decades and prolong usage of multiple drug regimen may induce substantial pathophysiological changes. Hence, This study was designed to evaluate the possible synergistic toxic effects of anti-hypertensive (carvedilol), and anti-inflammatory drug (celecoxib) alone and in combinations. Well-established MTT assay, Single Cell Gel Electrophoresis (SCGE) and Ames assay were employed to evaluate the toxicity at cellular level. Results from MTT assay on Vero cell line revealed that drug combinations have more pronounced anti-proliferative activity with combine IC50 value of 13.7:47.8... |

| Metabolism of anabolic androgenic steroids is important for its physiological effects. The aim was to investigate the effects of finasteride (a 5α-reductase inhibitor - 5αR) on cardiac and mutagenic effects promoted by ND. Male Wistar rats were separated into three groups: CONT, received the vehicles of ND and finasteride (Peanut oil+Saline); DECA group, received ND (20 mg.kg.week-1, i.m.), and DECAF received ND and finasteride (100 µg.kg-1, i.p.), for four weeks. After, hypertrophy, cytokines and Angiotensin Converting Enzyme (ACE) activity was determined in heart. Bone marrow was used for micronucleus evaluation. Treatment with ND promotes increase in cardiac hypertrophy, ACE activity and disbalance among pro- and anti-inflammatory cytokines, and... |

| ABSTRACT In the search for new anti-schistosomal agents, a series of fifteen ortho-nitrobenzyl derivatives was assayed in vitro against both the schistosomulum (somule) and adult forms of Schistosoma mansoni. Compounds 8 and 12 showed significant activity against somules at low micromolar concentrations, but none was active against adults. The SAR demonstrated that the compounds most active against the parasite were mutagenic to the human cell line RKO-AS45-1 only at concentrations 10- to 40-fold higher than the worm-killing dose. Given their electrophilicity, compounds were also screened as inhibitors of the S. mansoni cysteine protease (cathepsin B1) in vitro. Amides 5 and 15 exhibited a modest inhibition activity with values of 55.7 and 50.6 % at 100... |
