Use \Q and \E
$line =~ s/\Q$var2\E/$var1/;
(In this case you don't need the \E at the end, since it'll end at the end of the regexp anyway, but it's good to know if you do need it later.)

Also, I'm not sure what you mean by "I can't use ' instead of " because of algorytm specific", but if you need to interpolate variables and still not have to quote quotes.

my $line = <<"HTML"; <a href="/{HOST}?action">123</a>:</b><br>[img-smile "58-41" ":)"] HTML chomp $line;
Or you can use qq with just about any delimiter.
my $line = qq#<a href="/{HOST}?action">123</a>:</b><br>[img-smile "58- +41" ":)"]#;
