Teamwork in Cranial Base Surgery: A Feasible Task or a Utopian Dream.

In the past decade or perhaps a little earlier than that the concept of teamwork evolved among the circles of surgeons especially among those involved in complicated and time consuming surgeries. Skull base surgeries were one of those surgeries where the role of teamwork was acutely felt owing to innumerable specialties involved in the consummation of such surgeries. Although teamwork in this specialty is the need of the hour but, achieving the spirit of teamwork is not that easy and perhaps a challenging task. This manuscript tackles the much needed demand of teamwork in this arena of surgery and unveils whether such a teamwork is achievable or is just an utopian dream.

Molecular docking based screening of Listeriolysin-O for improved inhibitors.

Listeriolysine-O (LLO) is a 50KDa protein responsible for Listeria monocytogenes pathogenicity. The structure of LLO (PDB ID: 4CDB) with domains D1 to D4 is known. Therefore, it is of interest to identify conserved regions among LLO variants for destabilizing oligomerization (50 mer complex) of its monomers using appropriate inhibitors. Therefore, it is of interest to identify suitable inhibitors for inhibiting LLO. Previous reports suggest the use of flavanoids like compounds for inhibiting LLO. Our interest is to identify improved compounds to destabilize LLO oligomerization. We used a library (Zinc database) containing 200,000 drug-like compounds against LLO using molecular docking based screening. This resulted in five hits that were further analyzed for pharmacological properties. The hit #1 (2-methyloctadecane- 1, 3, 4-triol) was further refined using appropriate modifications for creating a suitable pharmacophore model LLO inhibition. The modified compound (1-(4-Cyclopent-3-enyl-6, 7-dihydroxy-8-hydroxymethyl-nona-2, 8-dienylideneamino)-penta-1,4-dien-3-one) shows fitting binding properties with LLO with no undesirable pharmacological properties such as toxicity.
