About the Lipinski's Rule of Five

The Lipinski's Rule of Five is a dedicated tool in our Chemistry category designed to help you check drug-likeness using rule of five in seconds. By automating the underlying mathematics, this utility eliminates manual calculations and provides reliable, instantaneous estimations.

Mathematical Principles & Calculation Steps

To compute the results, the calculation engine processes your custom inputs: Molecular Weight, log P (lipophilicity), H-Bond Donors, H-Bond Acceptors. Specifically, the calculations are evaluated using the standard relationship: MW ≤ 500, logP ≤ 5, HBD ≤ 5, HBA ≤ 10. All computations are performed locally within your secure browser session, ensuring absolute data privacy and instantaneous updates without any network delay.

Worked Step-by-Step Calculation Example

Worked Example Sandbox

For illustrative purposes, consider the following calculation using our default values. When we initialize the input fields with Molecular Weight = 350, log P (lipophilicity) = 3, H-Bond Donors = 2, H-Bond Acceptors = 5, the client-side calculator processes the numbers to resolve the formula and produce the final outputs: Rule Violations = 0 and Passes Lipinski? = true.

How to Use This Calculator

Set Inputs: Adjust the input values: Molecular Weight, log P (lipophilicity), H-Bond Donors to match your scenario.
Verify Outputs: The outputs: Rule Violations, Passes Lipinski? are updated in real-time on your screen.
Iterate: Change values and compare alternative scenarios to find your optimal result.
