.. class:: infomark **What this tool does** Align-it_ is a tool to align molecules according to their pharmacophores. A pharmacophore is an abstract concept based on the specific interactions observed in drug-receptor interactions: hydrogen bonding, charge transfer, electrostatic and hydrophobic interactions. Molecular modeling and/or screening based on pharmacophore similarities has been proven to be an important and useful method in drug discovery. The functionality of Align-it_ consists mainly of two parts. The first functionality is the generation of pharmacophores from molecules (use the tool **Pharmacophore generation** if you want to store these for further use). Secondly, pairs of pharmacophores can be aligned (the function of this tool). The resulting score is calculated from the volume overlap resulting of the alignments. .. _Align-it: http://silicos-it.be.s3-website-eu-west-1.amazonaws.com/software/align-it/1.0.4/align-it.html ----- .. class:: infomark **Input** * Example:: - database 30 31 0 0 0 0 0 0 0999 V2000 1.9541 1.1500 -2.5078 Cl 0 0 0 0 0 0 0 0 0 0 0 0 1.1377 -1.6392 2.1136 Cl 0 0 0 0 0 0 0 0 0 0 0 0 -3.2620 -2.9284 -1.0647 O 0 0 0 0 0 0 0 0 0 0 0 0 -2.7906 -1.9108 0.9092 O 0 0 0 0 0 0 0 0 0 0 0 0 0.2679 -0.2051 -0.3990 N 0 0 0 0 0 0 0 0 0 0 0 0 -2.0640 0.5139 -0.3769 C 0 0 0 0 0 0 0 0 0 0 0 0 -0.7313 0.7178 -0.0192 C 0 0 0 0 0 0 0 0 0 0 0 0 -2.4761 -0.6830 -1.1703 C 0 0 0 0 0 0 0 0 0 0 0 0 1.6571 -0.2482 -0.1795 C 0 0 0 0 0 0 0 0 0 0 0 0 -3.0382 1.4350 0.0081 C 0 0 0 0 0 0 0 0 0 0 0 0 -0.3728 1.8429 0.7234 C 0 0 0 0 0 0 0 0 0 0 0 0 -2.6797 2.5600 0.7506 C 0 0 0 0 0 0 0 0 0 0 0 0 -1.3470 2.7640 1.1083 C 0 0 0 0 0 0 0 0 0 0 0 0 2.5353 0.3477 -1.0918 C 0 0 0 0 0 0 0 0 0 0 0 0 2.1740 -0.8865 0.9534 C 0 0 0 0 0 0 0 0 0 0 0 0 -2.8480 -1.8749 -0.3123 C 0 0 0 0 0 0 0 0 0 0 0 0 3.9124 0.3058 -0.8739 C 0 0 0 0 0 0 0 0 0 0 0 0 3.5511 -0.9285 1.1713 C 0 0 0 0 0 0 0 0 0 0 0 0 4.4203 -0.3324 0.2576 C 0 0 0 0 0 0 0 0 0 0 0 0 -1.7086 -0.9792 -1.8930 H 0 0 0 0 0 0 0 0 0 0 0 0 -3.3614 -0.4266 -1.7676 H 0 0 0 0 0 0 0 0 0 0 0 0 -0.0861 -1.1146 -0.6780 H 0 0 0 0 0 0 0 0 0 0 0 0 -4.0812 1.2885 -0.2604 H 0 0 0 0 0 0 0 0 0 0 0 0 0.6569 2.0278 1.0167 H 0 0 0 0 0 0 0 0 0 0 0 0 -3.4382 3.2769 1.0511 H 0 0 0 0 0 0 0 0 0 0 0 0 -1.0683 3.6399 1.6868 H 0 0 0 0 0 0 0 0 0 0 0 0 4.6037 0.7654 -1.5758 H 0 0 0 0 0 0 0 0 0 0 0 0 3.9635 -1.4215 2.0480 H 0 0 0 0 0 0 0 0 0 0 0 0 5.4925 -0.3651 0.4274 H 0 0 0 0 0 0 0 0 0 0 0 0 -3.5025 -3.7011 -0.5102 H 0 0 0 0 0 0 0 0 0 0 0 0 - cutoff : 0.0 ----- .. class:: infomark **Output** The format of the output file is shown in the table below: +--------+-----------------------------------------------------------------------+ | Column | Content | +========+=======================================================================+ | 1 | Id of the reference structure | +--------+-----------------------------------------------------------------------+ | 2 | Maximum volume of the reference structure | +--------+-----------------------------------------------------------------------+ | 3 | Id of the database structure | +--------+-----------------------------------------------------------------------+ | 4 | Maximum volume of the database structure | +--------+-----------------------------------------------------------------------+ | 5 | Maximum volume overlap of the two structures | +--------+-----------------------------------------------------------------------+ | 6 | Overlap between pharmacophore and exclusion spheres in the reference | +--------+-----------------------------------------------------------------------+ | 7 | Corrected volume overlap between database pharmacophore and reference | +--------+-----------------------------------------------------------------------+ | 8 | Number of pharmacophore points in the processed pharmacophore | +--------+-----------------------------------------------------------------------+ | 9 | TANIMOTO score | +--------+-----------------------------------------------------------------------+ | 10 | TVERSKY_REF score | +--------+-----------------------------------------------------------------------+ | 11 | TVERSKY_DB score | +--------+-----------------------------------------------------------------------+ * Example:: - aligned Pharmacophores 3033 HYBL -1.98494 1.9958 0.532089 0.7 0 0 0 0 HYBL 3.52122 -0.309347 0.122783 0.7 0 0 0 0 HYBH -3.262 -2.9284 -1.0647 1 1 -3.5666 -3.7035 -1.61827 HDON 0.2679 -0.2051 -0.399 1 1 -0.076102 -0.981133 -0.927616 HACC -2.7906 -1.9108 0.9092 1 1 -2.74368 -1.94015 1.90767 $$$$ ]]> </help> <citations> <citation type="doi">10.1016/j.jmgm.2008.04.003</citation> </citations> </tool>
