The present invention relates to: coralmycin A and B, which are novel compounds exhibiting antimicrobial activity, an isomer thereof, a derivative thereof or a pharmaceutically acceptable salt thereof; a microorganism of the genusproducing the same; and an antimicrobial use thereof. The coralmycin A and B have very strong antimicrobial activity against antibiotic-resistant bacteria such as MRSA, QRSA, VRE, VISA, etc.;, which is a multidrug-resistant microorganism; and also against gram-positive microorganisms and gram-negative microorganisms. Therefore, the present invention can be very useful for prevention, treatment and alleviation of various microbial infections, and thus can be widely applied to the medical supply, quasi-drug, food, and feed industries.

Antimicrobial compound and use thereof

A polymerization initiator composition includes isomers of the polymerization initiator, thereby preventing instability and inertness of the polymerization initiator and physical property degradation of the SSBR, minimizing by-products and unreacted materials, and remarkably improving a conversion ratio. In addition, when the polymerization initiator composition according to the present invention is used, there is no need to add a polar additive separately upon polymer polymerization, since the polar additive is already added at the time of preparing the polymerization initiator. Further, the polymer initiator composition has high polarity so that the hydrophobic SSBR and the hydrophilic silica can be effectively dispersed.
