Last year we ran a program called the ChemDraw Challenge where people could suggest ideas and they went through commenting and voting processes. The first ideas from that should be materializing soon. Not that that helps, but those kind of forums are much better ways to suggest ideas so hopefully we will do something similar again.
Historically, needed fixes are slow to come, as additional updates of chemdraw and/or office may be needed to restore round-trip editing. Round-trip editing with MS Word 2016 was not restored until office-version 16.11.1 (180319), but only for Word: that is, not for Powerpoint nor Excel.

Beyond a full set of chemical structure essentials such as rings, bonds, chains, atoms, and functional group tools, ChemDraw Prime also allows you to calculate properties, create chemical and lab equipment templates, and utilize handy TLC Plate drawing tools. User-favorited hotkeys and shortcuts enable you to draw faster than ever before.
When trying to figure out graphics to make my poster, my mentor advised that I use a free trial Chem Draw. I had never heard of it before and up until then I had made some graphics on my poster stringing together different shapes on Microsoft PowerPoint. But there were just some figures that I was not able to make very easily. So when he told me about Chem Draw, at first it sounded like a program that could help me to draw chemical structures (which I needed as well) and I thought it ended there. But it was so much more! I geeked out when I saw all the different scientific structures and clip art that it automatically can draw for you, and you simply just make it the size you want. And it spans so many areas of science!

You will be notified via email when your preprint is posted online and a Digital Object Identifier (DOI) is assigned. Your preprint will remain globally available free to read whether the journal accepts or rejects your manuscript.
Journal policy Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the copyright holder. Authors accept full responsibility for the factual accuracy of the data presented and should obtain any authorization necessary for publication. As such the contents of the papers are the sole responsibility of the authors and publication shall not imply the concurrence of the editors or copyright holder. All papers are submitted to referees who advise the editor on the matter of acceptance in accordance with the high standards required, on the understanding that the subject matter has not been previously published and is not under consideration elsewhere. Referees will be asked to distinguish contributions meeting the above requirements and having an element of novelty, timeliness, and urgency that merits publication in the journal. We ask referees to help in the selection of articles that have this breadth and suggest that papers covering narrower aspects of the field be sent to journals specializing in those areas. Referee names are not disclosed, but their views are forwarded by the editor to the authors for consideration. Authors are encouraged to suggest names of several experts in the field when papers are first submitted or at any time in the evaluation process.
The Licensing group manages site licensed and individually-owned software for current faculty, staff, and enrolled students. This licensed software has been procured to assist Clemson University users with their daily computing tasks. We may keep titles on the list for 2 years or more after the license has expired because in many cases activating the license again only requires a maintenance fee versus the full product price. We want our users to know that this is an option if they see it on the list before purchasing.
More reviewers may be consulted in cases of opposing reports or when more clarification is needed. Articles needing significant revisions may be sent for further peer review before acceptance. Authors may appeal a rejection via communication with the Associate Editor. Our processes and policies can provide full details of the initial assessment process.
There is no page limit for communications in Analytical Methods, however the length should be commensurate with scientific content. Authors are encouraged to make full use of electronic supplementary information (ESI) in order to present more concise articles.
For authors who want to publish their article gold open access, Analytical Methods charges an article processing charge (APC) of 2,500 (+ any applicable tax). Our APC is all-inclusive and makes your article freely available online immediately, permanently, and includes your choice of Creative Commons licence (CC BY or CC BY-NC) at no extra cost. It is not a submission charge, so you only pay if your article is accepted for publication.
Authors can also publish in Analytical Methods via the traditional subscription model without needing to pay an APC. Articles published via this route are available to institutions and individuals who subscribe to the journal. Our standard licence allows you to make the accepted manuscript of your article freely available after a 12-month embargo period. This is known as the green route to open access.
RANKL (Receptor activator of nuclear factor kappa-B ligand), another member of the TNF superfamily, is the master mediator of osteoclast formation and bone resorption. Its specific inhibition with a monoclonal antibody (denosumab) effectively reduces the incidence of fractures in postmenopausal women[41] and emerges as the latest therapeutic achievement against osteoporosis. It has been demonstrated that SPD304 also binds to RANKL and inhibits RANKL-mediated osteoclastogenesis.[42] This motivated us to perform additional computations and biological assays for the T8 and T23 complexes with RANKL. In vitro proof of this second functionality thus established these two compounds as dual inhibitors[43] of TNF and RANKL. MD and free energy calculations for both structures and SPD304 in complex with TNF and RANKL were carried out to offer additional insight into the interactions that govern TNF and RANKL complex formation. Finally, direct and specific binding of the two compounds was confirmed both for TNF and RANKL, as well as their ability to inhibit the biologically-active trimer forms.
BMs were plated on 96-well plates at a density of 105 cells/well and treated with T8 and T23 at various concentrations, in the presence of M-CSF (25 ng/mL) for 48 hours. Cell viability was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay, which measures the ability of viable cells to reduce a soluble tetrazolium salt to an insoluble purple formazan precipitate.[63] After removal of the medium, each well was incubated with 0.5 mg/mL MTT (Sigma-Aldrich, St. Louis, MO) in serum-free α-MEM at 37C for 3 h. At the end of the incubation period, the medium was removed and the intracellular formazan was solubilized with 200 μL DMSO and quantified by reading the absorbance at 550 nm on a microplate reader (Optimax; Molecular Devices, Sunnyvale, CA). Cell viability (%) was expressed as a percentage of the negative control treated without compounds. LC50 values were calculated as mean SEM from three independent experiments.
The proposed models were validated both internally and externally in terms of goodness-of-fit, robustness and predictivity and were proven to successfully fulfill the criteria recommended by the Organization for Economic Cooperation and Development (OECD) for model validation.[88] For validation purposes, the dataset was separated into training and test sets. The small molecules included in the latter were kept as a blind set and were not used during the development of the model. 2ff7e9595c
