Do you understand more about bond types now then you did after reading the chapter in you textbook?

Chikungunya Virus: Emerging Targets and New Opportunities for Medicinal Chemistry - Journal of Medicinal Chemistry (ACS Publications)

Chikungunya Virus: Emerging Targets and New Opportunities for Medicinal Chemistry - Journal of Medicinal Chemistry (ACS Publications) | Chemistry | Scoop.it

Adel A. Rashad †, Suresh Mahalingam ‡, and Paul A. Keller *†

J. Med. Chem

DOI: 10.1021/jm400460d

Chikungunya virus is an emerging arbovirus that is widespread in tropical regions and is spreading quickly to temperate climates with recent epidemics in Africa and Asia and documented outbreaks in Europe and the Americas. It is having an increasingly major impact on humankind, with potentially life-threatening and debilitating arthritis. There is no treatment available, and only in the past 24 months have lead compounds for development as potential therapeutics been reported. This Perspective discusses the chikungunya virus as a significant, new emerging topic for medicinal chemistry, highlighting the key viral target proteins and their molecular functions that can be used in drug design, as well as the most important ongoing developments for anti-chikungunya virus research. It represents a complete picture of the current medicinal chemistry of chikungunya, supporting the development of chemotherapeutics through drug discovery and design targeting this virus.

Alfio Gangemi's curator insight, April 29, 2015 10:02 PM

Once again this contains great information for chemistry teachers. I think this is an excellent resource for engaging students and also trying to create new interest in chemistry. It has videos on a variety of the visually interesting and engaging chemistry experiments and their reactions. I will definitely use this resource in my classrooms at the beginning of and throughout the year to help generate interest and maintain engagement with my students.

A ‘Google’ for chemistry invents best path to new compounds in seconds

A ‘Google’ for chemistry invents best path to new compounds in seconds | Chemistry | Scoop.it

Giantic network links all known compounds and reactions together. 

 

Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network called Chematica — a chemical “Google” on steroids.

 

A decade in the making, the software optimizes syntheses of drug molecules and other important compounds, combines long (and expensive) syntheses of compounds into shorter and more economical routes, and identifies suspicious chemical recipes that could lead to chemical weapons.

 

The number of possible synthetic pathways leading to the desired target of a synthesis can be astronomical (10E19 pathways within five synthetic steps).

 

The Chematica network comprises some seven million chemicals connected by a similar number of reactions. A family of algorithms that searches and analyzes the network allows the chemist at his or her computer to easily tap into this vast compendium of chemical knowledge. And the system learns from experience, as more data and algorithms are added to its knowledge base.

Kathleen Cercone's curator insight, February 2, 2013 9:50 AM

Virtual Chemistry Experiments are a collection of interative web-based chemistry tutorials. The tutorials employ Physlets and Chemistry Applets to simulate experiments or depict molecular and atomic structure. The guiding concept is to involve the read in making observations and acquiring data, and then using this information to draw conclusions and infer chemical principles.

John Dalziel's curator insight, November 6, 2013 6:02 PM

This RSC (not the one I work for) is the largest non-government supporter of chemistry education in the UK. Their activities encompass formal and informal education from the cradle to the grave and are grouped into three key areas:
   - Schools and colleges
   - Higher Education (HE)
   - Continuing Professional Development (CPD)
They support the teaching of chemistry within the post-16 phases and their resources and materials are sent free to colleges in the UK and Ireland.
They also encourage initiatives to attract learners to the chemical sciences from all parts of society and raise awareness of potential careers. An advisory service and a variety of careers publications for learners and practitioners are available.
Note: Education in Chemistry is their bimonthly magazine produced for practitioners that includes a pupil supplement aimed at 14 - 18 year olds. This is also sent free to colleges and universities throughout the UK and Ireland.

Alfio Gangemi's curator insight, April 29, 2015 9:42 PM

This looks to be a fantastic resource for chemistry teachers. It has ideas for experiments and tools for calculation converters as well as teaching and tutoring help links. I believe this would help the teacher create more time to plan as because it seems to contain quite thorough and detailed information there is the potential that the teach would not have to look any further.
