First - please take care your theses work does not become public (i.e. it is not published or presented publicly in any other way). Once the work gets public it is no longer patentable.
Second - your university probably has something like Technology transfer department or at least a legal counsel. Please get in touch with those people, they can provide you with more information.
Last but not least, please be aware that for the work to constitute a patentable invention, the work must be a. novel, b. not obvious (it must contain an inventive step, not everybody in the field can come to your ideas), and c. it must have economic value, i.e. when applied in praxis, it can bring in (reasonable) profit. The profit potential is important because filing and maintaining a worldwide patent can be as expensive as a few hundred thousands USD. And defending it in case someone infringes your rights might be even more costly.
Dear Tarnima, I might not have been clear enough. Once a part of your thesis you want to patent is published in a journal, then it is generally no longer patentable, because it is no longer "new". From the patent point of view, the invention you want to patent must be "new", it means that it has not been publicly known at the time you file your patent application. It does not matter that the one making it public is you as the inventor. You are, however, free to publish your research after you have filed the application.
In some countries, there is a so called "grace period", that means that you have a few months or at maximum a year's time to file your invention with the patent office after you have published it in a journal. This grace period depends on the local, please consult with your university's legal counsel (lawyer).
I agree fully with the answers of Michal. Please note follows:
- If you publish a part of your thesis and if the experimental part is worthy to be reproduced, another scientists will try to find another way(s) to reproduce the drug(s).
If your synthesis needs toxic chemicals, one can try to produce the same drugs in a " green manner" and faster and cheaper than your synthesis.
On other part these scientists can try to patent these drug(s) before you.
P.e. see the patents disputs between Germany and Switzerland (Indigo) and
the discover of calcium carbide , per serendipity, during the search of another electrochemical way (calcium instead sodium for the bath) to produce Aluminium.
A trustworthy company is very difficult to find at this time.
