I've using Fedora as my main distro for a while now (FC 3) and here in Brazil, where I study Chemical Engineering, I started to use the excellent XDrawChem software, for drawing chemical structures and diagrams of reactions. I discovered, however, that the development of the program is freezed since November of 2005 [1] and the activities in the discutions lists had ceased a long time ago.
The future of this software seems uncertain and, until this point, poor promising, since improvements are not being made and it's outdated in comparison of what expect from a system that cares about constant evolution.
After some research and tests, I found the BkChem [2], that it is similar in functions, but it's uninterruptedly being developed and that, in fact, it had shown better results compared to the XdrawChem could obtain at the moment. The structures are more clear, the methods of drawing more refined and the plugins and tools already are compared with the ones that the XDrawChem had. The BkChem is distribuited under GPL and seems to be a good (and promising) substitute to the deceased XdrawChem.
