Background: Cinnamic acid is a key intermediate in shikimate and phenylpropanoid pathways. It is found both in free form, and especially in the form of esters in various essential oils, resins and balsams which are very important intermediates in the biosynthetic pathway of several natural products. The cinnamic derivatives play a vital role in the formation of commercially important intermediate molecules which are neces Read More

Background: Oximes and nitrofuranyl derivatives are particularly important compounds in medicinal chemistry. Thus, many researchers have been reported to possess antibacterial, antiparasitic, insecticidal and fungicidal activities. Methods: In this work, we report the synthesis and the biological activity against Mycobacterium tuberculosis H37RV of a series of fifty aryl oximes, ArCH=N-OH, I, and eight nitrofuranyl compounds, 2-ni Read More

Background: Radiotherapy is a treatment method for cancer mostly utilized for about 60% of cancer patients. Peripheral neuropathy is one of the severe complications of radiotherapy. Two stages of neuropathy will occur following irradiation; electrophysiological and biochemical variations as the first stage, while the second stage involves fibrosis of soft tissues surrounding the exposed nerve. This novel study aimed to investig Read More

Background: Enoyl acyl carrier protein reductase (InhA) is a validated target for Mycobacterium. It is an enzyme which is associated with the biosynthesis of mycolic acids in type II fatty acid synthase system. Mycobacterial cell wall majorly comprises mycolic acids, which are responsible for virulence of the microorganism. Several diphenyl ether derivatives have been known to be direct inhibitors of InhA. Objective: In the Read More

Background: The advantageous health effects of extracts from different types of plants have been known for centuries and the search for new natural extracts is very important at present. Methods: In this study, the antioxidant and the antimicrobial activities of Aesculus hippocastanum mother tincture (TM) against a range of foodborne bacteria were investigated to determine the major components and the action spect Read More

Background: Cancer incidence and mortality have been increasing and cancer is still the leading cause of death all over the world. Despite the enormous progress in cancer treatment, many patients died of ineffective chemotherapy and drug resistance. Therefore, the design and development of anti-cancer drugs with high efficiency and low toxicity is still one of the most challenging tasks. Tricyclic heterocycles, su Read More

Background: Despite a variety of drugs used to stop acute pain, problems related to their insufficient efficacy and undesirable side effects have remained unresolved. Therefore, the search for analgesics of new structural types, which combine high activity with low toxicity, is a topical issue. It is known that a number of compounds with a hydrogenated 2H-chromene skeleton exhibit significant analgesic activity in in vivo tests. M Read More

Background: A wide range of biological activity, relatively low toxicity and multiple pharmacological effects of triterpenoids are major advantages of these compounds in the prevention and treatment of various diseases. They include the lupane- type triterpenoids that proved to be a promising platform for the synthesis of analogs with a wide range of biological activities, including anti-inflammatory, antitumor, antiparasitic and Read More

Background: Xanthatin, fluoropyrimidine and thienopyrimidine, pyrazolopyrimidine, pyrimidine carboxamides, and SKLB1002 are reported as VEGFR2 tyrosine kinase inhibitors. Recently, many studies related to different heterocycles conjugated with dihydroquinazolinones are known to have very good biological activities. In this study, we are intended to explore the cytotoxic studies of piperidine conjugated dihydroquina Read More

Background: Thiohydantoins are an important class of heterocyclic compounds in drug discovery since they are related to a wide range of biological properties including antimicrobial activity. Objective: The objective of this study was to synthesize a series of thiohydantoins derived from Laminoacids and to evaluated their inhibitory effect on the growth of Gram-negative and Grampositive bacteria. Methods: All title comp Read More
