In silico screening and study of novel ERK2 inhibitors using 3D QSAR, docking and molecular dynamics.

ERK2 is a dual specificity protein kinase, part of the Ras/Raf/MEK/ERK signal transduction cascade. It forms an interesting target for inhibition based on its relationship with cell proliferation and oncogenesis. A 3D QSAR pharmacophore model (Hypo1) with high correlation (r=0.

Co-amoxiclav-induced Stevens Johnson syndrome in a child.

Stevens-Johnson syndrome is an uncommon life threatening disease generally induced by drugs. Antibiotics, mainly sulphonamides, are the most involved drugs in Stevens-Johnson syndrome in children. Co-amoxiclav is a well tolerated antibiotic.

Insight into TPMT(∗)23 mutation mis-folding using molecular dynamics simulation and protein structure analysis.

Thiopurine S-methyltransferase (TPMT) is an important enzyme that metabolizes thiopurine drugs. This enzyme exhibits a large number of interindividual polymorphism. TPMT(∗)23 polymorphism has been reported in a few cases in the world in co-dominance with TPMT(∗)3A.

Acetaminophen-induced cellulitis-like fixed drug eruption.

Acetaminophen is a widely used analgesic drug. Its adverse reactions are rare but severe. An 89-year-old man developed an indurated edematous and erythematous plaque on his left arm 1 day after acetaminophen ingestion.
