Students will be able to connect molecular geometry to enzyme target site shapes. Students will be able to design 3D-printable shapes in CAD. Students will be able to describe how small molecule drugs can be designed to act as inhibitors. Students will be able to explain the difference between competitive and noncompetitive (allosteric) inhibitors. #123d design vs tinkercad how toDuring the activity, students may need guidance on how to best design the pieces for easy printing. #123d design vs tinkercad softwareThe activity can be used as an exploration though to learn how to use these pieces of software themselves. Optionally, students may be given an introduction to using basic CAD software such as Tinkercad or 123D Design. They should have a basic understanding of protein structure and the importance of this structure in relation to function. Students should already be familiar with enzymes, active sites, and the basics of competitive and noncompetitive inhibition. In this activity, students will learn about inhibitors and how scientists design molecules that will fit into active sites or surface sites on proteins. Pharmaceutical chemistry is a fun way to get students interested in learning about molecular biology and proteins. This will then lead to a discussion of the real-world process of drug design. Lastly, students can connect their designs to molecular geometry by trying to recreate their drug designs using the basic shapes that molecules can form. The advantages and disadvantages of these slight differences (such as half-life in the body and side-effects) can be discussed. Once printed, students can compare the different solutions to the same target sites, leading to a discussion of how many drugs for the same problem bind to the same site but have slightly different structures (i.e. In this process, the students will also learn strategies for successful printing and how/when to use infill, rafts, and supports. Successful small molecule drugs should fit snugly into the target sites. Once students design molecules that can inhibit the protein, the models can be printed and tested with the the printed enzyme. One of the noncompetitive sites, when a "drug molecule" binds to it, closes off an active site (see pictures) to demonstrate how allosteric binding can change the structure of the enzyme. The model includes sites for competitive and non-competitive inhibition of the enzyme. #123d design vs tinkercad downloadStudents will download the STL file into a program such as Tinkercad and will use the CAD software to design "molecules" that could fit into the target sites and block the enzyme from binding to its normal small molecules. The enzyme has multiple active sites and surface binding sites. Note that Tinkercad does not have options like orthographic view or a proper text tool compared to 123D.This printable "enzyme" with multiple target sites is designed to teach students the basics of small molecule drug design as well as serve as an introduction to using basic CAD design software to build 3D-printable objects. I recommend it for beginners who want to try out Tinkercad but may not be ready to commit. When creating complex designs, 123D can sometimes run very slowly and Iâve often experienced crashes. #123d design vs tinkercad free123D vs Other Platformsġ23D is a free software mainly targeted towards beginners or users with some basic CAD experience. Simply enter the dimensions of your 3D printerâs plate and youâre good to go. However, before exporting, remember to convert it back to millimeters! Edit gridĮdit Grid allows you to set the grid size to match your 3D printer. If you want to use inches, you can by adjusting the unit. Otherwise, you could end up making a huge error. Knowing this, be careful when drawing custom designs. UnitsģD printers use millimeters as the default unit for measurements. If required, the user can turn it off and drag the object randomly around the grid. Snap decides the intervals that an object can be moved/rotated on the grid. After selecting the primitive from the menu, you much first input the dimensions of the object and then the object can be dropped on the grid. One cool aspect of primitives is that users can adjust their size. Primitives are pre-made 3D models that users can start a design with, but they are limited. Meshmixer and 123D Make are both handy tools I use to check my model before exporting it to my 3D printer. I only work with STL but highly recommended that users figure out their 3D printerâs requirements and choose the appropriate format based on that. With Import, users can import a 3D model or a sketch/2D image in SVG format and then extrude this sketch to 3D.Įxporting as a 3D model provides four format options: STL, SAT, X3D, and VRML. 123Dx extension, which means these files can only open in 123D. Note: Files saved to your computer are saved with a. The tabs shown by the green arrow are Undo (ctrl+Z) and Redo (ctrl+Y) and come in very handy when designing a model.
