In this assay, the evaluation of lipophilicity of four ACE-inhibitors and hydrochlorothiazide (HCTZ) with RP-TLC on cellulose layers was described using three binary solvent systems. The selected ACE inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with HCTZ. In addition, the linea...

Arthritis refers to different medical conditions associated with disorder of the primary structures that determine joint functions such as bones, cartilage and synovial membranes. Drug discovery and delivery to retard the degeneration of joint tissues are challenging. Current treatments of different arthritis involves administration of ideal non-steroidal anti-inflammatory drugs (NSAIDs) but ar...

       In this study, we investigated the interactive effects of intraperitoneal (i.p.) injections of three different phosphodiesterase inhibitors (PDEIs) on morphine-induced analgesia in mice using tail-flick method. Subcutaneous administration of morphine (1, 3 and 6 mg/kg) caused significant antinociceptive effects in a dose dependent manner. Administration of pentoxifylline (12.5, 25, 50 an...

background: the mechanism of hypoglycemic and hypolipidemic activities of pyrus biossieriana buhse leaf extract (pbble) and its phytochemical component arbutin, have not been well determined. the present study was performed to understand the hypoglycemic activity mechanisms of pbble and arbutin more clearly.methods: in vitro enzymatic carbohydrate digestion with pbble and arbutin was assessed u...

coronary heart disease is the leading cause of death and disability in adults. the association between acute coronary syndrom (acs) and elevated serum high sensitivity c-reactive protein (hscrp) suggests that chronic inflammation of the coronary arterial wall may play an important role. a number of drugs used in the treatment of cardiovascular disease reduce serum crp. it* is therefore possible...

gliobalstoma multiforme (gbm) or grade 4 astrocytoma is the most malignant form of primary brain tumor. treatment of glioblastoma is difficult despite of surgery, radiotherapy and chemotherapy. patients with glioblastoma survive for less than 12 months. considering to biology function of glioblastoma, researchers have recently offered new therapeutic approaches such as cannabinoid therapy for g...

the urgent need of neuraminidase inhibitors (ni) has provided an impetus for understanding the structure requisite at molecular level. our search for selective inhibitors of neuraminidase has led to the identification of pharmacophoric requirements at various positions around acyl thiourea pharmacophore. the main objective of present study is to develop selective ni, with least toxicity and dru...

In this article it is reported about: cholinesterases, their ac!ion and their importance in anaesthesiology and intensiv care units. The cholinesterases inhibitors and treat­ment of cholinesterases deficiency and their reactivation is also discussed.
