The inhibition of ribonuclease Bi by 3'-N-hydroxyurea-3'-deoxythymidine 5'-phosphate is enhanced by 30-fold in the presence of Zn(2+). Thus, an N-hydroxyurea nucleotide can recruit Zn(2+) to inhibit the enzymatic activity of a ribonuclease. This result engenders a general strategy for the inhibition of non-metalloenzymes by metal complexes.
New series of spiroindeno[1,2-b]pyrido[2,3-d]pyrimidine-5,3′-indolines as new urease inhibitors were synthesized by the catalytic procedure in high yield and short reaction time. In this method, biacidic carbon was prepared as a novel heterogeneous acid and was subsequently used as an efficient catalyst in this synthesis. The inhibitory activities of synthesized compounds were tested against Ja...
Nanotechnology has revolutionized diagnosis and treatment of cancers. Breast cancer is oneof the most prevalent cancers among women. Paclitaxel and hydroxyurea are important drugsin treatment of breast cancer but their use is limited due to a series of significant side effects.On the other hand, nanoliposomes are widely used as nanocarriers for targeted drug delivery.In this study, cytotoxic ef...

OBJECTIVE The aim of this study was to compare the efficacy and toxicity of different concurrent chemoradiotherapy (CCRT) regimens in the treatment of advanced cervical cancer (CC) by adopting a network meta-analysis. METHODS We searched PubMed and Cochrane Library from the inception of these databases to September 2016, and all cohort studies (CSs) related to different CCRT regimens in the t...
BACKGROUND We compared daily pain, home analgesic use, and utilization among ambulatory adults in the randomized multicenter study of hydroxyurea in sickle cell anemia (MSH). We related the fetal hemoglobin (HbF) hydroxyurea response to these response variables. METHODS Patients rated their sickle cell pain intensity (0-9), use of analgesics, and visits for pain daily. Diaries were collected ...
