$ file
CellDesigner-4.1-linux-installer.bin: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, stripped
$ strings CellDesigner-4.1-linux-installer.bin | grep '$Info'
$Info: This file is packed with the UPX executable packer http://upx.sf.net $
$ upx -d CellDesigner-4.1-linux-installer.bin > /dev/null
upx: CellDesigner-4.1-linux-installer.bin: CantUnpackException: header corrupted 2

Looks like an UPX-packed executable with an additional wrapper (might be
another layer of encryption/compression) or a modified version of UPX.
This is probably not so easy to unpack and needs more investigation.
