+-----------+-----------+
| sender | recipient |
+-----------+-----------+
| admin | user1 |
| user1 | admin |
+-----------+-----------+
What i have tried?
UPDATE messages
SET (sender='newname' OR recipient='newname')
WHERE (sender='admin' OR recipient='admin')
ERROR:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an
error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near
'(sender='dsfdsx' OR recipient='dsfdsx') WHERE (sender='admin' OR
recipient='admi' at line 1
What should be changed?

You can use conditional expressions CASE..WHEN to UPDATE accordingly:
UPDATE messages
SET
sender = CASE sender WHEN 'admin' THEN 'newname' ELSE sender END,
recipient = CASE recipient WHEN 'admin' THEN 'newname' ELSE recipient END
WHERE
sender = 'admin' OR recipient = 'admin'
