Vapur: A Search Engine to Find Related Protein - Compound Pairs in COVID-19 Literature

1 code implementation EMNLP (NLP-COVID19) 2020 Abdullatif Köksal, Hilal Dönmez, Rıza Özçelik, Elif Ozkirimli, Arzucan Özgür

Coronavirus Disease of 2019 (COVID-19) created dire consequences globally and triggered an intense scientific effort from different domains.

Exploring Data-Driven Chemical SMILES Tokenization Approaches to Identify Key Protein-Ligand Binding Moieties

no code implementations26 Oct 2022 Asu Büşra Temizer, Gökçe Uludoğan, Rıza Özçelik, Taha Koulani, Elif Ozkirimli, Kutlu O. Ulgen, Nilgün Karalı, Arzucan Özgür

To this end, we build a language-inspired pipeline that treats high affinity ligands of protein targets as documents and selects key chemical words making up those ligands based on tf-idf weighting.

Exploiting Pretrained Biochemical Language Models for Targeted Drug Design

1 code implementation2 Sep 2022 Gökçe Uludoğan, Elif Ozkirimli, Kutlu O. Ulgen, Nilgün Karalı, Arzucan Özgür

On the other hand, large amounts of unlabeled protein sequences and chemical compounds are available and have been used to train language models that learn useful representations.

Exploring Chemical Space using Natural Language Processing Methodologies for Drug Discovery

no code implementations10 Feb 2020 Hakime Öztürk, Arzucan Özgür, Philippe Schwaller, Teodoro Laino, Elif Ozkirimli

Text-based representations of chemicals and proteins can be thought of as unstructured languages codified by humans to describe domain-specific knowledge.

WideDTA: prediction of drug-target binding affinity

no code implementations4 Feb 2019 Hakime Öztürk, Elif Ozkirimli, Arzucan Özgür

In addition, the results showed that, given the protein sequence and ligand SMILES, the inclusion of protein domain and motif information as well as ligand maximum common substructure words do not provide additional useful information for the deep learning model.

ChemBoost: A chemical language based approach for protein-ligand binding affinity prediction

1 code implementation2 Nov 2018 Rıza Özçelik, Hakime Öztürk, Arzucan Özgür, Elif Ozkirimli

Our aim is to process the patterns in SMILES as a language to predict protein-ligand affinity, even when we cannot infer the function from the sequence.

Drug Discovery Word Embeddings

A novel methodology on distributed representations of proteins using their interacting ligands

no code implementations30 Jan 2018 Hakime Öztürk, Elif Ozkirimli, Arzucan Özgür

We showed that ligand-based protein representation, which uses only SMILES strings of the ligands that proteins bind to, performs as well as protein-sequence based representation methods in protein clustering.

DeepDTA: Deep Drug-Target Binding Affinity Prediction

4 code implementations30 Jan 2018 Hakime Öztürk, Elif Ozkirimli, Arzucan Özgür

The results show that the proposed deep learning based model that uses the 1D representations of targets and drugs is an effective approach for drug target binding affinity prediction.
